abstract = {Farm Management Information Systems (FMIS) are an important core component of modern farming companies as they allow, e.g., to document activities, create fertilization plans, and feed digital equipment with required data. Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

abstract = {Computer Emergency Response Teams (CERTs) have been established in the public sector globally to provide advisory, preventive and reactive cybersecurity services for government agencies, citizens, and businesses. Nevertheless, their responsibility of monitoring, analyzing, and communicating cyber threats and security vulnerabilities have become increasingly challenging due to the growing volume and varying quality of information disseminated through public and social channels. Based on a design case study conducted from 2021 to 2023, this paper combines three iterations of expert interviews (N=25), design workshops (N=4) and cognitive walkthroughs (N=25) to design an automated, cross-platform and real-time cybersecurity dashboard. By adopting the notion of cyber situational awareness, the study further extracts user requirements and design heuristics for enhanced threat intelligence and mission awareness in CERTs, discussing the aspects of source integration, data management, customizable visualization, relationship awareness, information assessment, software integration, (inter-)organizational collaboration, and communication of stakeholder warnings.},

abstract = {Misinformation poses a recurrent challenge for video-sharing platforms (VSPs) like TikTok. Obtaining user perspectives on digital interventions addressing the need for transparency (e.g., through indicators) is essential. This article offers a thorough examination of the comprehensibility, usefulness, and limitations of an indicator-based intervention from an adolescents’ perspective. This study (𝑁 = 39; aged 13-16 years) comprised two qualitative steps: (1) focus group discussions and (2) think-aloud sessions, where participants
engaged with a smartphone-app for TikTok. The results offer new insights into how video-based indicators can assist adolescents’ assessments. The intervention received positive feedback, especially for its transparency, and could be applicable to new content. This paper sheds light on how adolescents are expected to be experts while also being prone to video-based misinformation, with limited understanding of an intervention’s limitations. By adopting
teenagers’ perspectives, we contribute to HCI research and provide new insights into the chances and limitations of interventions for VSPs.},

abstract = {Amidst the ongoing anti-military protests in Myanmar since 2021, there is a noticeable research gap on ICT-supported activism. Generally, ICTs play an important role during political crises in conjunction with activists’ practices on the ground. Inspired by Resource Mobilization Theory, I conducted qualitative interviews (N=16) and a qualitative online survey (N=34), which demonstrate the intersection between analog and digital domains, showcasing the ingenuity of the activists, and the rapid adoption of ICTs in a country that has experienced a digital revolution within the last few years. As not all people were able to protest on-the-ground, they acted as keyboard fighters to organize protests, to share information, and to support the civil disobedience movement in Myanmar. The study identifies, inter alia, the need for better offline applications with wider coverage in times of internet shutdowns, applications that cannot be easily identified during physical controls, and providing free and secure VPN access.},

abstract = {Browser cookies, especially those from third parties, pose a threat to individual privacy. While it is possible in principle to control the number of cookies accepted, this choice is often neither usable nor truly informed. To address this issue, this study used semi-structured interviews (N=19) to identify attitudes and user requirements to develop an alternative personalised cookie banner, which was evaluated in an online experiment (N=157). The cookie banner explanations were tailored to the privacy knowledge of three groups of users: low, medium and high. The online experiment measured cookie choices and perceived usability of the cookie banner across three groups: an experimental group that viewed the novel cookie banner with personalisation (personalised privacy assistant), a control group that viewed the novel cookie banner without personalisation (privacy assistant) and a control group that viewed the standard cookie banner provided by the website. The results indicate that the novel cookie banner (with or without personalisation) generally resulted in significantly fewer accepted cookies and increased usability compared to the standard cookie window. In addition, the personalised cookie banner resulted in significantly fewer accepted cookies and higher usability than the non-personalised cookie banner. These results suggest that tailoring cookie banners to users' privacy knowledge can be an effective approach to empowering users to make informed choices and better protect their privacy.},

abstract = {In many scenarios users have to communicate sensitive data with third parties such as doctors, lawyers, insurance companies, social workers or online shops. Handing over personal data is necessary to use those services but the delegation of tasks to increase efficiency still poses the risk that personal data might be leaked. To minimize this risk and further enhance the privacy of users, we propose an interaction concept that uses layered encryption of messages to provide a trade-off between privacy and usability. Users can choose which data is additionally encrypted in an inner layer, say, for the eyes of their doctor only, and which data is available in an outer (encrypted or unencrypted) layer for all staff members. Another benefit is the hiding of sensitive data from package inspection or crawling algorithms over emails, while less critical parts can still be processed by these systems via the partial access. To investigate this concept, we derive relevant use cases for form-based communication over email from a quantitative pre-study with 1011 participants, showing that general practitioners are the most suitable use case. We developed demonstrators for this use case and evaluated them in a qualitative study with 42 participants. Our results show that the possibility of minimizing the propagation of sensitive data through additional encryption is highly appreciated and the usage of form-based communication is a promising approach for the digital transformation.},

While an extensive body of research on this topic exists, researchers are confronted with a diverse research landscape spanning multiple disciplines. This review systematizes the landscape of user-centered misinformation interventions to facilitate knowledge transfer, identify trends, and enable informed decision-making. Over 3,700 scholarly publications were screened and a systematic literature review (N=108) was conducted. A taxonomy was derived regarding intervention design (e.g., binary label), user interaction (active or passive), and timing (e.g., post exposure to misinformation). We provide a structured overview of approaches across multiple disciplines, and derive six overarching challenges for future research.},

With a mixed-method design that includes a representative survey of the German population, a design workshop and an app evaluation experiment, this study investigates users’ preferences regarding non-acute preparedness alerts’ inclusion in crisis apps and the effectiveness of Nudging in this context. The experiment shows that while the social influence nudge had no significant effect compared to the control group without a nudging condition, the confrontational nudge increased the number of taken recommended preparedness measures. The evaluation indicates that the preparedness alerts increased users’ knowledge and their motivation to use a warning app. This motivation is, in contrast, decreased when the messages are perceived as a disruption. While many oppose push notifications, favor finding persuasively designed preparedness advice in a separate menu or as an optional notification.},

abstract = {Cyberspace is a fragile construct threatened by malicious cyber operations of different actors, with vulnerabilities in IT hardware and software forming the basis for such activities, thus also posing a threat to global IT security. Advancements in the field of artificial intelligence accelerate this development, either with artificial intelligence enabled cyber weapons, automated cyber defense measures, or artificial intelligence-based threat and vulnerability detection. Especially state actors, with their long-term strategic security interests, often stockpile such knowledge of vulnerabilities and exploits to enable their military or intelligence service cyberspace operations. While treaties and regulations to limit these developments and to enhance global IT security by disclosing vulnerabilities are currently being discussed on the international level, these efforts are hindered by state concerns about the disclosure of unique knowledge and about giving up tactical advantages. This leads to a situation where multiple states are likely to stockpile at least some identical exploits, with technical measures to enable a depletion process for these stockpiles that preserve state secrecy interests and consider the special constraints of interacting states as well as the requirements within such environments being non-existent. This paper proposes such a privacy-preserving approach that allows multiple state parties to privately compare their stock of vulnerabilities and exploits to check for items that occur in multiple stockpiles without revealing them so that their disclosure can be considered. We call our system ExTRUST and show that it is scalable and can withstand several attack scenarios. Beyond the intergovernmental setting, ExTRUST can also be used for other zero-trust use cases, such as bug-bounty programs.},

abstract = {Agriculture is subject to high demands regarding resilience as it is an essential component of the food production chain. In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur, such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers (N = 52) and a survey with participants from the agricultural sector (N = 118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture. The result is a low robustness capacity, as our analysis concludes with the risk of food production losses.},

This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

Across the individual sub-studies, almost 10,000 people are surveyed including representative studies in the Netherlands, Germany, the UK and Italy. The work empirically shows that social media is increasingly important for emergency services, both for prevention and during crises; that private use of social media is a driving force in shaping opinions for organisational use; and that citizens have high expectations towards authorities, especially monitoring social media is expected, and sometimes responses within one hour. Depending on the risk culture, the data show further differences, e.g. whether the state (Germany) or the individual (Netherlands) is seen as primarily responsible for coping with the situation.},

abstract = {In the digital age, the vision of autonomous vehicles (AVs) is vibrant. Research is being conducted worldwide to inte-grate AVs into our everyday lives in the future, spending consid-erable amounts of money in the development process. Actors from both engineering as well as social sciences are involved in this re-search, with technical disciplines strongly dominating. In addition to perceived progress of numerous newly developed technologies such as AVs, challenges should also be referred to. According to research analysis, the transferability of autonomous cars to the military sphere seems to be frequently forgotten or ignored (dual-use). Since not much research has been conducted in Germany on the potential deployment of autonomous driving development steps into military domains, 25 semi-structured interviews with de-velopers and researchers and actors involved in the field, were conducted in 2020. The paper identifies that the majority of re-spondents interviewed were aware of general existing dual-use de-bates, however, few had reflected about dual-use issues regarding a possible transfer of their own development processes in the con-text of autonomous driving to military applications, intensively. One reason is the small-scale nature of research, another is the complexity of the field, which enables the engineer’s alienation from their responsibility for the artefacts’ use. Moreover, it has become clear that hardly any conversations among colleagues oc-cur about possible misuse and that no standardized policy guide-lines exist, which provide information about possible risk. To raise dual-use awareness, scientific contributions, risk education, and interdisciplinary discussions are essential.},

abstract = {The backbone network of submarine communication cables (SCC) carries 98\% of international internet traffic. Coastal and island states strongly depend on this physical internet infrastructure to provide internet connectivity. Although about 100 SCC breakdowns of human or natural origin occur at yearly average, a literature review reveals that there is no approach to assess individual state vulnerability to SCC failure in global comparison. In this article, the global SCC network is modeled based on publicly available data. Besides the analysis of the global network properties, a focus is put on remaining bandwidth capacities in three different failure scenario simulations of SCC breakdowns. As a result, this study identifies 15 highly vulnerable states and overseas territories, and another 28 territories that are classified as partially vulnerable to SCC failures. Since economic market decisions shape the structure of the SCC network, an uneven distribution of redundancies and the resulting vulnerability of disadvantaged economies can be confirmed. Therefore, the study's findings may contribute to a better assessment of the necessity of preventive protection measures of critical telecommunication infrastructures in states and territories characterized by high and medium vulnerability.},

abstract = {Technological progress can disrupt domains
and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

One prominent approach for measuring spillover effects is based on the analysis of patent citation networks. Taking social media analytics and knowledge economics into account, this paper presents a complementary approach to quantify spillover effects from defense to civilian research and development, analyzing 513 employment biographies from the social network LinkedIn. Using descriptive network analysis, we investigate the emigration of personnel of the German defense industry to other civilian producers. Thereby, our study reveals that in the last decade, employees of defense suppliers have changed positions significantly less often, with 3.24 changes on average than professionals who have worked more than 50\% of their jobs in the civilian sector, having changed 4.61 times on average. Our work illustrates the churn behavior and how spillover effects between defense and civilian sectors can be measured using social career networks such as LinkedIn.},

abstract = {Since the emergence of so-called fake news on the internet and in social media, platforms such as Facebook have started to take countermeasures, and researchers have begun looking into this phenomenon from a variety of perspectives. A large number of scientific work has investigated ways to detect fake news automatically. Less attention has been paid to the subsequent step, i.e., what to do when you are aware of the inaccuracy of claims in social media. This work takes a user-centered approach on means to counter identified mis- and disinformation in social media. We conduct a three-step study design on how approaches in social media should be presented to respect the users' needs and experiences and how effective they are. As our first step, in an online survey representative for some factors to the German adult population, we enquire regarding their strategies on handling information in social media, and their opinion regarding possible solutions — focusing on the approach of displaying a warning on inaccurate posts. In a second step, we present five potential approaches for countermeasures identified in related work to interviewees for qualitative input. We discuss (1) warning, (2) related articles, (3) reducing the size, (4) covering, and (5) requiring confirmation. Based on the interview feedback, as the third step of this study, we select, improve, and examine four promising approaches on how to counter misinformation. We conduct an online experiment to test their effectiveness on the perceived accuracy of false headlines and also ask for the users' preferences. In this study, we find that users welcome warning-based approaches to counter fake news and are somewhat critical with less transparent methods. Moreover, users want social media platforms to explain why a post was marked as disputed. The results regarding effectiveness are similar: Warning-based approaches are shown to be effective in reducing the perceived accuracy of false headlines. Moreover, adding an explanation to the warning leads to the most significant results. In contrast, we could not find a significant effect on one of Facebook's current approaches (reduced post size and fact-checks in related articles).},

Social media allow emergency services to reach the public easily in the context of crisis communication and receive valuable information (e.g. pictures) from social media data. However, the vast amount of data generated during large-scale incidents can lead to issues of information overload and quality. To mitigate these issues, this paper proposes the semi-automatic creation of alerts including keyword, relevance and information quality filters based on cross-platform social media data. We conducted empirical studies and workshops with emergency services across Europe to raise requirements, then iteratively designed and implemented an approach to support emergency services, and performed multiple evaluations, including live demonstrations and field trials, to research the potentials of social media-based alerts. Finally, we present the findings and implications based on semi-structured interviews with emergency services, highlighting the need for usable configurability and white-box algorithm representation.},

Our comparison of the four countries allows for an interpretation of divergent behavior across countries with respect to risk cultures as well as expanding the respective model to social media contexts. At the same time, our findings stress that across the four European countries participants assessed similar advantages like dissemination of information and barriers like false rumors with respect to use social media during emergencies.

This paper examines the use of social media during the European Floods of 2013 and proposes a novel cross-social-media application for volunteers. Besides comprehensive analysis of volunteer communities, interviews were conducted with "digital volunteers" such as Facebook moderators of disaster-related groups. Based on the challenges identified, we designed and implemented the cross-social-media application "XHELP", which allows information to be both, acquired and distributed cross-media and cross-channel. The evaluation with 20 users leads to further design requirements for applications aiming to support volunteer moderators during disasters.},

While virtual groups seem to easily form and collaborate, the engagement of real volunteers is decreasing according to the perception of professionals.

abstract = {The ongoing challenge of misinformation on social media motivates ongoing efforts to find effective countermeasures.
In this study, we evaluated the potential of personalised nudging to reduce the sharing of misinformation on social media, as personalised support has been successfully applied in other areas of critical information handling.
In an online experiment (N = 396) exposing users to social media posts, we assessed the degree of misinformation sharing between groups receiving (1) no nudges, (2) non-personalised nudges, and (3) personalised nudges. Personalisation was based on three psychometric dimensions - general decision-making style, consideration of future consequences, need for cognition - to assign the most appropriate nudge from a pool of five nudges.
The results showed significant differences (p {\textless} .05) between all three groups, with the personalised nudge group sharing the least misinformation. Detailed analyses at the nudge level revealed that one nudge was universally effective and two nudges were effective only in their personalised form.
The results generally confirm the potential of personalisation, although the effect is limited in scope.
These findings shed light on the nuanced results of nudging studies, highlight the benefits of personalisation, and raise ethical considerations regarding the privacy implications of personalisation and those inherent in nudges.},

Whereas research in computer-supported cooperative work has extensively explored collaboration of and automation for content moderators, there are no works that focus on reporting centers. Based on expert interviews with their staff (N=15), this study finds that most German centers share a collaborative workflow, of which multiple tasks are heavily dependent on inter-organizational exchange. However, there are differences in their implementation of monitoring, content assessment, automation technology adoption, and external collaborators. As the centers are faced with diverse challenges, such as borderline case assessment, psychological burdens, limited visibility, conflicting goals with other actors, and manual repetitive work, our study contributes with nine implications for designing and researching supportive technologies. They provide suggestions for improving hate speech gathering and reporting, researching hate speech prioritization and assessment algorithms, and designing case processing systems. Beyond that, we outline directions for research on inter-organizational collaboration.},

abstract = {In conflict-ridden environments, timely and accurate information is critical for those dealing with the dynamic of events. When individuals have to flee, it becomes evident that refugees frequently rely on information and communication technologies (ICT) for information acquisition, travel coordination, and maintaining connections with related parties. Based on 17 interviews, this research explores how Ukrainian refugees, who sought protection in Germany due to the 2022 Russian full-scale invasion, use ICT before, during, and after their flight. By providing empirical findings, the results show in depth how contextual factors, such as infrastructural instability, privacy concerns and an advanced digitalization, interrelate with user behaviors. Analyzing the multifaceted civilian ICT use in the context of war and flight, this exploratory research contributes to the existing research on HCI in migration contexts and connects to several topics of CSCW. By contrasting case specifics, this work highlights what makes Ukraine a special case in this research area. Furthermore, this paper examines both existing and emerging affordances of ICT in the context of flight, and identifies the crucial role of messenger groups for information gathering in all phases of the flight. Lastly, collaborative dimensions of the identified affordances are discussed.},

abstract = {Active learning is designed to minimize annotation efforts by prioritizing instances that most enhance learning. However, many active learning strategies struggle with a 'cold start' problem, needing substantial initial data to be effective. This limitation often reduces their utility for pre-trained models, which already perform well in few-shot scenarios. To address this, we introduce ActiveLLM, a novel active learning approach that leverages large language models such as GPT-4, Llama 3, and Mistral Large for selecting instances. We demonstrate that ActiveLLM significantly enhances the classification performance of BERT classifiers in few-shot scenarios, outperforming both traditional active learning methods and the few-shot learning method SetFit. Additionally, ActiveLLM can be extended to non-few-shot scenarios, allowing for iterative selections. In this way, ActiveLLM can even help other active learning strategies to overcome their cold start problem. Our results suggest that ActiveLLM offers a promising solution for improving model performance across various learning setups.},

abstract = {The field of cybersecurity is evolving fast. Security professionals are in need of intelligence on past, current and - ideally - on upcoming threats, because attacks are becoming more advanced and are increasingly targeting larger and more complex systems. Since the processing and analysis of such large amounts of information cannot be addressed manually, cybersecurity experts rely on machine learning techniques. In the textual domain, pre-trained language models like BERT have proven to be helpful as they provide a good baseline for further fine-tuning. However, due to the domain-knowledge and the many technical terms in cybersecurity, general language models might miss the gist of textual information. For this reason, we create a high-quality dataset and present a language model specifically tailored to the cybersecurity domain which can serve as a basic building block for cybersecurity systems. The model is compared on 15 tasks: Domain-dependent extrinsic tasks for measuring the performance on specific problems, intrinsic tasks for measuring the performance of the internal representations of the model as well as general tasks from the SuperGLUE benchmark. The results of the intrinsic tasks show that our model improves the internal representation space of domain words compared to the other models. The extrinsic, domain-dependent tasks, consisting of sequence tagging and classification, show that the model performs best in cybersecurity scenarios. In addition, we pay special attention to the choice of hyperparameters against catastrophic forgetting, as pre-trained models tend to forget the original knowledge during further training.},

abstract = {Adversarial examples, capable of misleading machine learning models into making erroneous predictions, pose significant risks in safety-critical domains such as crisis informatics, medicine, and autonomous driving. To counter this, we introduce a novel textual adversarial example method that identifies falsely learned word indicators by leveraging explainable AI methods as importance functions on incorrectly predicted instances, thus revealing and understanding the weaknesses of a model. Coupled with adversarial training, this approach guides models to adopt complex decision rules when necessary and simpler ones otherwise, enhancing their robustness. To evaluate the effectiveness of our approach, we conduct a human and a transfer evaluation and propose a novel adversarial training evaluation setting for better robustness assessment. While outperforming current adversarial example and training methods, the results also show our method's potential in facilitating the development of more resilient transformer models by detecting and rectifying biases and patterns in training data, showing baseline improvements of up to 23 percentage points in accuracy on adversarial tasks. The code of our approach is freely available for further exploration and use.},

While it is possible in principle to control the number of cookies accepted, this choice is often neither usable nor truly informed. To address this issue, this study used semi-structured interviews (N=19) to identify attitudes and user requirements to develop an alternative personalised cookie banner, which was evaluated in an online experiment (N=157). The cookie banner explanations were tailored to the privacy knowledge of three groups of users: low, medium and high. The online experiment measured cookie choices and perceived usability of the cookie banner across three groups: an experimental group that viewed the novel cookie banner with personalisation (personalised privacy assistant), a control group that viewed the novel cookie banner without personalisation (privacy assistant) and a control group that viewed the standard cookie banner provided by the website. The results indicate that the novel cookie banner (with or without personalisation) generally resulted in significantly fewer accepted cookies and increased usability compared to the standard cookie window. In addition, the personalised cookie banner resulted in significantly fewer accepted cookies and higher usability than the non-personalised cookie banner. These results suggest that tailoring cookie banners to users' privacy knowledge can be an effective approach to empowering users to make informed choices and better protect their privacy.},

abstract = {In Germany, both law enforcement agencies and dedicated reporting centers engage in various activities to counter illegal online hate speech. Due to the high volume of such content and against the background of limited resources, their personnel can be confronted with the issue of information overload. To mitigate this issue, technologies for information filtering, classification, prioritization, and visualization offer great potential. However, domainspecific classification schemes that differentiate subtypes of online hate speech are a prerequisite for the development of such assistive tools. There is a gap in research with regard to an empirically substantiated classification scheme for subtypes of hate speech for the German law enforcement and reporting center domain. Based on a review of relevant computer science publications (N=24) and qualitative interviews with practitioners (N=18), this work investigates practice-relevant subtypes of hate speech and finds that it is primarily differentiated with regard to targeted group affiliations, the conveyance of an immediate security threat, and criminal relevance. It contributes to the state of research with an empirically grounded online hate speech classification scheme for German law enforcement agencies and reporting centers (C1) and five implications for the user-centered design of hate speech classification tools (C2).},

abstract = {Nowadays, the problem of point-to-point encryption is solved by
the wide adaptation of protocols like TLS. However, challenges

such as PGP and secure messengers like Signal, suffer from issues
like 1) low usability, 2) small user base, 3) dependence on central
service providers, and 4) susceptibility to backdoors. Concerns over
legally mandated backdoors are rising as the US and EU are propos-
ing new surveillance regulations requiring chat monitoring. We
present a new E2EE solution called Encrypted MultiChannel Com-
munication ( EMC2), based on 𝑛-out-of-𝑛 secret sharing. EMC2 splits
messages into multiple secret shares and sends them through in-
dependent channels. We show that multiple independent channels
exist between users and EMC2 provides E2EE with no single point of
trust, no setup, and is understandable by the general public. Our so-
lution complements existing tools and strengthens the case against
legally enforced backdoors by demonstrating their ineffectiveness.},

Ethical considerations play a pivotal role in (social science) research, safeguarding, amongst others, the rights and well-being of participants and ensuring research integrity. Despite notable progress in promoting research ethics, German research institutions still need to significantly improve their ethics review processes. To address these challenges, this article emphasizes the need for expanding the current management of research ethics and implementing what we call ?Institutionalized Research Ethics Practices?? (IREPs), which include but go beyond the scope of common Institutional Review Boards (IRBs). Drawing on two workshops with researchers and IRB members, and a systematic review of existing IRBs in the German social sciences, we propose concrete recommendations for developing and enhancing IREPs, including a conducive environment, accessibility, fairness, and fostering expertise (CAFE). These enhancements aim to strengthen Germany?s research ethics infrastructure and promote responsible and ethical research practices in the social sciences.},

abstract = {In many applications and websites people use in their everyday life, their privacy and data is threatened, e.g., by script tracking during browsing. Although researchers and companies have developed privacy-enhancing technologies (PETs), they are often difficult to use for lay users. In this paper, we conducted a literature review to classify users into different support personas based on their privacy competence and privacy concern. With developers of PETs in mind, support personas were envisioned to facilitate the customization of software according to the support needs of different users. In order to demonstrate the usefulness of support personas and based on workshop sessions with 15 participants, we designed a browser extension which supports users with the issue of script tracking by providing different user interfaces for different support personas. The following qualitative evaluation with 31 participants showed that the developed UI elements worked as intended for the different support personas. Therefore, we conclude the concept of support personas is useful in the development process of usable applications that enhance the privacy of the users while also educating them and thus potentially increasing their privacy literacy.},

As not all people were able to protest on-the-ground, they acted as keyboard fighters to organize protests, to share information, and to support the civil disobedience movement in Myanmar. The study identifies, inter alia, the need for better offline applications with wider coverage in times of internet shutdowns, applications that cannot be easily identified during physical controls, and providing free and secure VPN access.},

This study (𝑁 = 39; aged 13-16 years) comprised two qualitative steps: (1) focus group discussions and (2) think-aloud sessions, where participants
engaged with a smartphone-app for TikTok. The results offer new insights into how video-based indicators can assist adolescents’ assessments. The intervention received positive feedback, especially for its transparency, and could be applicable to new content. This paper sheds light on how adolescents are expected to be experts while also being prone to video-based misinformation, with limited understanding of an intervention’s limitations. By adopting
teenagers’ perspectives, we contribute to HCI research and provide new insights into the chances and limitations of interventions for VSPs.},

abstract = {Misinformation presents a challenge to democracies, particularly in times of crisis. One way in which misinformation is spread is through voice messages sent via messenger groups, which enable members to share information on a larger scale. Gaining user perspectives on digital misinformation interventions as countermeasure after detection is crucial. In this paper, we extract potential features of misinformation in voice messages from literature, implement them within a program that automatically processes voice messages, and evaluate their perceived usefulness and comprehensibility as user-centered indicators.We propose 35 features extracted from audio files at the character, word, sentence, audio and creator levels to assist (1) private individuals in conducting credibility assessments, (2) government agencies faced with data overload during crises, and (3) researchers seeking to gather features for automatic detection approaches. We conducted a think-aloud study with laypersons (N = 20) to provide initial insight into how individuals autonomously assess the credibility of voice messages, as well as which automatically extracted features they find to be clear and convincing indicators of misinformation. Our study provides qualitative and quantitative insights into valuable indicators, particularly when they relate directly to the content or its creator, and uncovers challenges in user interface design.},

This review systematizes the landscape of user-centered misinformation interventions to facilitate knowledge transfer, identify trends, and enable informed decision-making. Over 3,700 scholarly publications were screened and a systematic literature review (N=108) was conducted. A taxonomy was derived regarding intervention design (e.g., binary label), user interaction (active or passive), and timing (e.g., post exposure to misinformation). We provide a structured overview of approaches across multiple disciplines, and derive six overarching challenges for future research.},

users already use autonomously to assess a tweet’s credibility. Subsequently, in a think-aloud study participants
qualitatively evaluated the identified indicators in terms of perceived comprehensibility and usefulness. While
a number of indicators were found to be particularly comprehensible and useful (e.g., claim for absolute truth

people with entrenched conspiracy theory views. We derive four implications for digitally supporting users in
dealing with misleading information, especially during crises.},

By analysing the posting behaviour of the government-appointed TJ institutions on Facebook, we show how general TJ aims and opportunities for citizen participation were promoted in 2019. Our analysis reveals that the organisations rarely address topics related to reconciliation and that active online participation and two-way communication are rather scarce. Instead, Facebook is mainly used by the TJ organisations to increase solidarity with victims and disseminate information about their work and the TJ process. Reflecting on existing literature on TJ and social media participation, we identify great potential for expanding TJ goals and community engagement on social media, to use it as a resource for facilitating the TJ processes, creating exchange, and enabling participation.},

On the contrary, terrorists may recruit new members and disseminate ideologies, and social bots may influence social and political processes. Based on the notions of cultural violence and cultural peace as well as the phenomena of fake news, terrorism and social bots, this exploratory review firstly presents human cultural inter-ventions in social media (e.g. dissemination of fake news and terroristic propaganda) and respective countermeasures (e.g. fake news detection and counter-narratives). Sec-ondly, it discusses automatic cultural interventions realised via social bots (e.g. astro-turfing, misdirection and smoke screening) and countermeasures (e.g. crowdsourcing and social bot detection). Finally, this chapter concludes with a range of cultural inter-ventions and information and communication technology (ICT) in terms of actors and intentions to identify future research potential for supporting situational assessments during conflicts.},

To respond to emerging threats, CERTs must gather information in a timely and comprehensive manner. But the volume of sources and information leads to information overload. This paper contributes to the question of how to reduce information overload for CERTs. We propose clustering incoming information as scanning this information is one of the most tiresome, but necessary, manual steps. Based on current studies, we establish conditions for such a framework. Different types of evaluation metrics are used and selected in relation to the framework conditions. Furthermore, different document embeddings and distance measures are evaluated and interpreted in combination with clustering methods. We use three different corpora for the evaluation, a novel ground truth corpus based on threat reports, one security bug report (SBR) corpus, and one with news articles. Our work shows, it is possible to reduce the information overload by up to 84.8\% with homogeneous clusters. A runtime analysis of the clustering methods strengthens the decision of selected clustering methods. The source code and dataset will be made publicly available after acceptance.},

abstract = {In today’s world, cyber-attacks are becoming more frequent and thus proactive protection against them is becoming more important. Cyber Threat Intelligence (CTI) is a possible solution, as it collects threat information in various information sources and derives stakeholder intelligence to protect one’s infrastructure. The current focus of CTI in research is the clear web, but the dark web may contain further information. To further advance protection, this work analyzes the dark web as Open Source Intelligence (OSINT) data source to complement current CTI information. The underlying assumption is that hackers use the dark web to exchange, develop, and share information and assets. This work aims to understand the structure of the dark web and identify the amount of its openly available CTI related information. We conducted a comprehensive literature review for dark web research and CTI. To follow this up we manually investigated and analyzed 65 dark web forum (DWF), 7 single-vendor shops, and 72 dark web marketplace (DWM). We documented the content and relevance of DWFs and DWMs for CTI, as well as challenges during the extraction and provide mitigations. During our investigation we identified IT security relevant information in both DWFs and DWMs, ranging from malware toolboxes to hacking-as-a-service. One of the most present challenges during our manual analysis were necessary interactions to access information and anti-crawling measures, i.e., CAPTCHAs. This analysis showed 88\% of marketplaces and 53\% of forums contained relevant data. Our complementary semi-automated analysis of 1,186,906 onion addresses indicates, that the necessary interaction makes it difficult to see the dark web as an open, but rather treat it as specialized information source, when clear web information does not suffice.},

abstract = {Like many sectors, agriculture is experiencing a continuous digitalization, i.e. an increase in data-driven technologies used. In contrast to companies of other critical infrastructures – e.g. energy or telecommunication – a typical farm is comparatively small and often run as a family business.
Accordingly, the demands on farming technology, its implementation, and regulations are different in many terms.
Furthermore, the circumstances that influence crisis risks and crisis management are different in agriculture – and as digitalization introduces new potential risks, this process should be reviewed critically.
Currently, the most advanced approaches for agriculture are typically referred to as smart farming and agriculture 4.0, which incorporate more precise cultivation with less manual effort.
But such new agriculture technology developments usually lack an assessment about its impact on the sector's resilience and dependencies on other infrastructures.
The research domains of crisis informatics and IT security mostly focuses on other topics, apart from agriculture.
The resilience research in agriculture itself is currently intensifying, however, this line of research focuses more on problems resulting from the climate crisis and social change.
For these reasons it remains unclear, how digitalization impacts the resilience of food production and food safety.
Therefore, it is not well researched which technological developments may lead to undesired effects in the future.
How modern systems should be designed to allow for both, positive impacts on efficiency, and prevention of negative effects in terms of reduced resilience capacities, is also not answered by current literature.
The aim of the present work is to close this research gap at the intersection of agriculture, digitalization, and resilience.
To answer the question to what extent current technologies used by farmers are at risk of failure, the dissertation first presents a snapshot of the resilience state of agricultural companies and the technologies used.
This involves interviews with stakeholders, mainly farmers, as well as surveying security issues of the LoRaWAN protocol, a transmission technology especially useful for agricultural Internet of Things.
Which desires of farmers exist regarding software focusing on aspects of business continuity and secured operations, is another open question.
This dissertation aims to also answer this question with empirical methods, mainly focus groups and usability tests.
Then the rise of Internet of Things in agriculture raises another question, whether such technologies acquired for smart farming could also have benefits for resilience against internet-connection-lost situations.
This question is answered by empirical evaluation of LoRaWAN range characteristics in agricultural landscapes, as well as artifact generation for resilient communication channels on top of LoRaWAN transmission devices.
Several findings are derived from the conducted research:
There is a lack of understanding of how strong the used tools in agriculture depend on ICT, and many tools require a working internet connection.
Moreover, IT employed by agricultural enterprises presents security concerns similar to those encountered in other domains.
Based on these findings, developments, and evaluations of new software approaches are presented:
Derived design criteria and own system designs that allow for modern data-driven business operations, including IoT integration based on LoRaWAN.
The developed solutions show an increase in resilience capacities by enhancing the communication possibilities in crisis situations.
The detected low absorption capacities against communication infrastructure outages shows room for improvement.
To improve agricultural ITs' resilience, software engineers could use the concepts and designs of this dissertation for their product development, like a modular offline-capable farm management storage that allows an exchange of small data in an autarkic manner via commodity LoRaWAN hardware.
But also technology advisors and farmers benefit from the technological analyses and suggestions embedded in this work, like using multiple LoRaWAN gateways with an overlapping coverage to mitigate security vulnerabilities.},

title = {Resilient {Smart} {Farming}: {Crisis}-{Capable} {Information} and {Communication} {Technologies} for {Agriculture}},
url = {http://tuprints.ulb.tu-darmstadt.de/26496/},
abstract = {Like many sectors, agriculture is experiencing a continuous digitalization, i.e. an increase in data-driven technologies used. In contrast to companies of other critical infrastructures – e.g. energy or telecommunication – a typical farm is comparatively small and often run as a family business.
Accordingly, the demands on farming technology, its implementation, and regulations are different in many terms.
Furthermore, the circumstances that influence crisis risks and crisis management are different in agriculture – and as digitalization introduces new potential risks, this process should be reviewed critically.
Currently, the most advanced approaches for agriculture are typically referred to as smart farming and agriculture 4.0, which incorporate more precise cultivation with less manual effort.
But such new agriculture technology developments usually lack an assessment about its impact on the sector's resilience and dependencies on other infrastructures.
The research domains of crisis informatics and IT security mostly focuses on other topics, apart from agriculture.
The resilience research in agriculture itself is currently intensifying, however, this line of research focuses more on problems resulting from the climate crisis and social change.
For these reasons it remains unclear, how digitalization impacts the resilience of food production and food safety.
Therefore, it is not well researched which technological developments may lead to undesired effects in the future.
How modern systems should be designed to allow for both, positive impacts on efficiency, and prevention of negative effects in terms of reduced resilience capacities, is also not answered by current literature.
The aim of the present work is to close this research gap at the intersection of agriculture, digitalization, and resilience.
To answer the question to what extent current technologies used by farmers are at risk of failure, the dissertation first presents a snapshot of the resilience state of agricultural companies and the technologies used.
This involves interviews with stakeholders, mainly farmers, as well as surveying security issues of the LoRaWAN protocol, a transmission technology especially useful for agricultural Internet of Things.
Which desires of farmers exist regarding software focusing on aspects of business continuity and secured operations, is another open question.
This dissertation aims to also answer this question with empirical methods, mainly focus groups and usability tests.
Then the rise of Internet of Things in agriculture raises another question, whether such technologies acquired for smart farming could also have benefits for resilience against internet-connection-lost situations.
This question is answered by empirical evaluation of LoRaWAN range characteristics in agricultural landscapes, as well as artifact generation for resilient communication channels on top of LoRaWAN transmission devices.
Several findings are derived from the conducted research:
There is a lack of understanding of how strong the used tools in agriculture depend on ICT, and many tools require a working internet connection.
Moreover, IT employed by agricultural enterprises presents security concerns similar to those encountered in other domains.
Based on these findings, developments, and evaluations of new software approaches are presented:
Derived design criteria and own system designs that allow for modern data-driven business operations, including IoT integration based on LoRaWAN.
The developed solutions show an increase in resilience capacities by enhancing the communication possibilities in crisis situations.
The detected low absorption capacities against communication infrastructure outages shows room for improvement.
To improve agricultural ITs' resilience, software engineers could use the concepts and designs of this dissertation for their product development, like a modular offline-capable farm management storage that allows an exchange of small data in an autarkic manner via commodity LoRaWAN hardware.
But also technology advisors and farmers benefit from the technological analyses and suggestions embedded in this work, like using multiple LoRaWAN gateways with an overlapping coverage to mitigate security vulnerabilities.},

abstract = {Farm Management Information Systems (FMIS) are an important core component of modern farming companies as they allow, e.g., to document activities, create fertilization plans, and feed digital equipment with required data. Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

abstract = {Agriculture is experiencing continuous digitalization, with an increasing importance of data for the tools used.
In contrast to other critical infrastructures, the average agricultural business has a small number of employees. The requirements for agricultural technology, its implementation and the regulations therefore differ from other critical infrastructures. The effects of current trends such as smart farming on the resilience of the sector and dependencies on other infrastructures remain unclear. But some aspects of agricultural digitalization must be viewed critically in order to avoid security risks in future: Products must have secure default settings and the need for cloud connectivity should be questioned more frequently – both for stronger security and resilience to infrastructure failures and the high need for data protection in agriculture. With the right developments, digitalization can not only be made secure, but also have a positive effect on the resilience and efficiency of farms.},

abstract = {In many scenarios users have to communicate sensitive data with third parties such as doctors, lawyers, insurance companies, social workers or online shops. Handing over personal data is necessary to use those services but the delegation of tasks to increase efficiency still poses the risk that personal data might be leaked. To minimize this risk and further enhance the privacy of users, we propose an interaction concept that uses layered encryption of messages to provide a trade-off between privacy and usability. Users can choose which data is additionally encrypted in an inner layer, say, for the eyes of their doctor only, and which data is available in an outer (encrypted or unencrypted) layer for all staff members. Another benefit is the hiding of sensitive data from package inspection or crawling algorithms over emails, while less critical parts can still be processed by these systems via the partial access. To investigate this concept, we derive relevant use cases for form-based communication over email from a quantitative pre-study with 1011 participants, showing that general practitioners are the most suitable use case. We developed demonstrators for this use case and evaluated them in a qualitative study with 42 participants. Our results show that the possibility of minimizing the propagation of sensitive data through additional encryption is highly appreciated and the usage of form-based communication is a promising approach for the digital transformation.},

abstract = {Internet of Things (IoT) devices have become increasingly important within the smart home domain, making the security of the devices a critical aspect. The majority of IoT devices are black-box systems running closed and pre-installed firmware. This raises concerns about the trustworthiness of these devices, especially considering that some of them are shipped with a microphone or a camera. Remote attestation aims at validating the trustworthiness of these devices by verifying the integrity of the software. However, users cannot validate whether the attestation has actually taken place and has not been manipulated by an attacker, raising the need for HCI research on trust and understandability. We conducted a qualitative study with 35 participants, investigating trust in the attestation process and whether this trust can be improved by additional explanations in the application. We developed an application that allows users to attest a smart speaker using their smartphone over an audio channel to identify the attested device and observe the attestation process. In order to observe the differences between the applications with and without explanations, we performed A/B testing. We discovered that trust increases when additional explanations of the technical process are provided, improving the understanding of the attestation process.},

However, current methods are neither user-friendly nor scalable for large groups of users. In response, we introduce PairSonic, a novel group pairing protocol that extends trust from physical encounters to online communication. PairSonic simplifies the pairing process by automating the tedious verification tasks of previous methods through an acoustic out-of-band channel using smartphones' built-in hardware. Our protocol not only facilitates connecting users for computer-supported collaboration, but also provides a more user-friendly and scalable solution to the authentication ceremonies currently used in end-to-end encrypted messengers like Signal or WhatsApp. PairSonic is available as open-source software: https://github.com/seemoo-lab/pairsonic},

We evaluate the usability of two secure contact exchange systems: the current state of the art, SafeSlinger, and our newly designed protocol, PairSonic, which extends trust from physical encounters to spontaneous online communication. Our lab study (N=45) demonstrates PairSonic's superior usability, automating the tedious verification tasks from previous approaches via an acoustic out-of-band channel. Although participants significantly preferred our system, minimizing user effort surprisingly decreased the perceived security for some users, who associated security with complexity. We discuss user perceptions of the different protocol components and identify remaining usability barriers for CSCW application scenarios.},

It defines practical measures that enable treaty members to check the treaty compliance by observing, counting or moni-toring specific actions and their accordance with the respective rules. In contrast to his-torical examples of former military technologies, cyberspace features some unique char-acteristics making it hard to apply established measures. The chapter describes these peculiarities and assesses distinguishing problems compared to selected verification measures for nuclear, biological and chemicals weapons technology. Yet, cyberspace is a human-made domain and adjusting its technical setting, rules and principles may help to reduce the threat of ongoing militarisation. Offering some alternatives, the chapter elaborates on suitable and measurable parameters for this domain and presents potential-ly useful verification approaches.},

To illustrate these further, this chapter elaborates on the necessity of arms control and presents some historical examples, including an overview of existing measures of arms control. Extrapolating from these, the general architecture of arms control regimes and the complex issue of establishing and verifying compliance with agreements will be discussed, not least with respect to cyberspace.

abstract = {Cyberspace, already a few decades old, has become a matter of course for most of us, part of our everyday life. At the same time, this space and the global infrastructure behind it are essential for our civilizations, the economy and administration, and thus an essential expression and lifeline of a globalized world. However, these developments also create vulnerabilities and thus, cyberspace is increasingly developing into an intelligence and military operational area – for the defense and security of states but also as a component of offensive military planning, visible in the creation of military cyber-departments and the integration of cyberspace into states' security and defense strategies. In order to contain and regulate the conflict and escalation potential of technology used by military forces, over the last decades, a complex tool set of transparency, de-escalation and arms control measures has been developed and proof-tested. Unfortunately, many of these established measures do not work for cyberspace due to its specific technical characteristics. Even more, the concept of what constitutes a weapon – an essential requirement for regulation – starts to blur for this domain. Against this background, this thesis aims to answer how measures for the de-escalation of state-led conflicts in cyberspace and arms control of cyberweapons can be developed. In order to answer this question, the dissertation takes a specifically technical perspective on these problems and the underlying political challenges of state behavior and international humanitarian law in cyberspace to identify starting points for technical measures of transparency, arms control and verification. Based on this approach of adopting already existing technical measures from other fields of computer science, the thesis will provide proof of concepts approaches for some mentioned challenges like a classification system for cyberweapons that is based on technical measurable features, an approach for the mutual reduction of vulnerability stockpiles and an approach to plausibly assure the non-involvement in a cyberconflict as a measure for de-escalation. All these initial approaches and the questions of how and by which measures arms control and conflict reduction can work for cyberspace are still quite new and subject to not too many debates. Indeed, the approach of deliberately self-restricting the capabilities of technology in order to serve a bigger goal, like the reduction of its destructive usage, is yet not very common for the engineering thinking of computer science. Therefore, this dissertation also aims to provide some impulses regarding the responsibility and creative options of computer science with a view to the peaceful development and use of cyberspace.},

Sie widmete sich dem Wandel von Technologien, deren Rolle in Kriegen und Konflikten sowie Fragen der Rüstungskontrolle. Ausgerichtet wurde die englischsprachige Konferenz von TraCe, einem hessischen BMBF-Forschungsverbund zu Transformationen politischer Gewalt, vom DFG-Sonderforschungsbereich CROSSING zu kryptografiebasierten Sicherheitslösungen und vom Forschungsverbund Naturwissenschaft, Abrüstung und internationale Sicherheit FONAS.
Der Krieg Russlands gegen die Ukraine macht die Bedeutung der Friedens- und Konfliktforschung und deren technische Dimension, unter anderem, offensichtlich. Bereits 2019 hat der Wissenschaftsrat als wichtigstes wissenschaftspolitisches Beratungsgremium in Deutschland seine Empfehlungen zur Weiterentwicklung der Friedens- und Konfliktforschung veröffentlicht. Darin weist er auf einen dringenden Handlungsbedarf zur Stärkung der naturwissenschaftlich-technischen Friedens- und Konfliktforschung hin. Die Konferenzreihe Science · Peace · Security möchte einen kleinen Beitrag dazu leisten. Sie wurde 2019 in Darmstadt gegründet, fand 2021 an der RWTH Aachen statt, und soll 2025 am Forschungszentrum Jülich stattfinden.},

How can dual-use awareness and regulation help to mitigate the risks to peace and security on the national and international levels? As cyberspace has been declared a military domain, IT is increasingly important for civil and military infrastructures. How can researchers, developers and decision-makers make sure that IT is not misused to cause harm? This has been discussed as the dual-use problem for nuclear, biological and chemical technologies. This chapter introduces different dual-use concepts and illustrates by considering cryptography, intrusion software, and artificial intelligence how governance measures, including export control, are applied. Further, approaches of technology assessment, with a focus on the design process, are presented. The chapter also provides insight into the implementation of dual-use assessment guidelines at TU Darmstadt, the so-called Civil Clause.},

abstract = {The development of artificial intelligence and autonomous functions in the military domain has an immense impact on technologies being developed by the private defence industry. Defence firms contribute to the narratives and visions on autonomous weapon systems and the future of warfare, e.g. in the form of strategic marketing of their products. However, their role has so far been understudied, especially regarding autonomous weapon systems. As the normative debate revolves around aspects of human control, this work examines the narratives of (meaningful) human control in the marketing of autonomous military systems by defence manufacturers. Based on a comprehensive content analysis of twenty defence firms, we identified three main narratives, which envision autonomy as a military advantage, the role of the human in the future of warfare, and human-machine teaming. Based on the results, we argue that defence companies reproduce and adapt narratives which shape expectations and visions of human control of autonomous weapon systems in anticipation of emerging norms for (meaningful) human control. However, without specifications and verification mechanisms, there is no indication that human control will be meaningful.},

abstract = {In crises such as the COVID-19 pandemic, it is crucial to support users when dealing with social media content. Considering digital resilience, we propose a web app based on Social Network Analysis (SNA) to provide an overview of potentially misleading vs. non-misleading content on Twitter, which can be explored by users and enable foundational learning. The latter aims at systematically identifying thematic patterns which may be associated with misleading information. Additionally, it entails reflecting on indicators of misleading tweets which are proposed to approach classification of tweets. Paying special attention to non-expert users of social media, we conducted a two-step Think Aloud study for evaluation. While participants valued the opportunity to generate new knowledge and the diversity of the application, qualities such as equality and rapidity may be further improved. However, learning effects outweighed individual costs as all users were able to shift focus onto relevant features, such as hashtags, while readily pointing out content characteristics. Our design artifact connects to learning-oriented interventions regarding the spread of misleading information and tackles information overload by a SNA-based plug-in.},

abstract = {With developments in Artificial Intelligence widely framed as security concern in both military and civilian realms, governments have turned their attention to regulating and governing AI. In a study of US, Chinese, and EU AI documents, we go beyond instrumental understandings of AI as a technological capability, which serves states' self-interests and the maintenance of their (supra)national security. Our specific interest lies in how AI policies tap into both problem-solving approaches and affective registers to achieve both physical as well as ontological security. We find that in governmental visions, AI is perceived as a capability that enhances societal, and geopolitical interests while its risks are framed as manageable. This echoes strands within Human-Computer Interaction that draw on human-centered perceptions of technology and assumptions about human-AI relationships of trust. Despite different cultural and institutional settings, the visions of future AI development are shaped by this (shared) understanding of human-AI interaction, offering common ground in the navigation of innovation policies.},

abstract = {Digital technology and smartphones provide great opportunities to support crisis response measures. During the COVID-19 pandemic, many countries introduced contact tracing apps (CTAs) to prevent the virus’s spread and identify infection clusters. Because wide acceptance is necessary for these apps to work, it has been a subject of research. Past research often highlighted the role of trust for acceptance and suggested that technical transparency by opening the source code can help to build trust. For this reason, we studied the acceptance of two German apps: the Corona-Warn-App (CWA), which was developed as open-source software early on, and the Luca app, which did not publish the source code initially. We conducted a multinomial logistic regression testing effects on the adoption of (1) only the CWA, (2) only the Luca app, or (3) both apps. As predictors, we considered the role of trust in the app publisher and the government and controlled for predictors relevant to past research. We found trust to have a significant effect on the acceptance of the apps. A self-reported understanding of the term “open-source software” and a perceived threat by COVID-19 had a positive effect for the Corona-Warn-App or both apps but not for the Luca app alone. Being from Eastern Germany lowered the acceptance of the Luca app or both apps. Our findings can add to previous CTA acceptance research and provide insights for policymakers for future digital crisis measures, especially for populations comparable to the German population regarding government trust and privacy attitudes.},

Derived from the taxonomy, we divide more than 100 methods into 12 different groupings and give state-of-the-art references expounding which methods are highly promising by relating them to each other.

abstract = {Landwirtschaft als essenzieller Teil der Nahrungsmittelproduktion gehört zu den kritischen Infrastrukturen (KRITIS). Dementsprechend müssen die eingesetzten Systeme für einen widerstandsfähigen Betrieb ausgelegt sein. Dies gilt auch für die auf landwirtschaftlichen Betrieben eingesetzte Software, die Sicherheits- und Resilienzkriterien genügen muss. Jedoch ist die Zunahme an Software zu beobachten, welche eine permanente Internetkonnektivität erfordert, d. h. eine stabile Verbindung zu Servern oder Cloud-Applikationen ist für deren Funktionsweise erforderlich. Dies stellt eine erhebliche Schwachstelle hinsichtlich der Resilienz dar und kann bei Ausfällen der Telekommunikationsinfrastruktur zu großen Problemen führen. Mit Entwicklungen aus dem Bereich Resilient Smart Farming (RSF) zeigen wir, wie Datenhaltung nach dem Offline-First-Prinzip gestaltet werden kann. Ein zentraler Bestandteil hierbei ist das Resilient Edge Computing (REC) und die entwickelte HofBox: ein Mini-Server, der das Datenmanagement im Betrieb übernimmt und mittels innovativer Open-Source basierender Container-Technologie (Open Horizon) umsetzt. Dadurch werden in Zukunft weitere Anwendungsfälle innerhalb der landwirtschaftlichen Produktions- und Wertschöpfungskette durch Public-Private-Partnership-Modelle realistisch und realisierbar.},

Although many IoT sensors, such as smoke detectors or security cameras, are available and governmental crisis warning systems are in place, little is known about how to warn appropriately in smart home environments. We created a Raspberry Pi based prototype with a speaker, a display, and a connected smart light bulb. Together with a focus group, we developed a taxonomy for warning messages in smart home environments, dividing them into five classes with different stimuli. We evaluated the taxonomy using the Experience Sampling Method (ESM) in a field study at participants' (N = 13) homes testing 331 warnings. The results show that taxonomy-based warning stimuli are perceived to be appropriate and participants could imagine using such a warning system. We propose a deeper integration of warning capabilities into smart home environments to enhance the safety of citizens.},

abstract = {The digitalisation of critical infrastructure has increased the risk of large-scale cyber incidents. In contrast to the management of conventional emergencies by established civil protection organisations involving volunteers in Germany, few response capacities exist for these events. The concept of a volunteer force for cyber security could close this protection gap. However, such involvement also poses practical and ethical challenges. By conducting interviews with computer science students (N = 11), this paper analyses potential volunteers’ attitudes towards ethical implications of a cyber volunteer force, as well as practical aspects that might motivate or hinder their participation. A qualitative
content analysis reveals that students are largely unaware of potential dilemmas connected to vulnerabilities handling and national cybersecurity interests. Ethical guidelines and means of motivating and encouraging potential volunteers
are discussed.},

abstract = {Warning apps are used by many to receive warnings about imminent disasters. However, their potential for increasing awareness about general hazards and for increasing preparedness is currently underused. With a mixed-method design that includes a representative survey of the German population, a design workshop and an app evaluation experiment, this study investigates users’ preferences regarding non-acute preparedness alerts’ inclusion in crisis apps and the effectiveness of Nudging in this context. The experiment shows that while the social influence nudge had no significant effect compared to the control group without a nudging condition, the confrontational nudge increased the number of taken recommended preparedness measures. The evaluation indicates that the preparedness alerts increased users’ knowledge and their motivation to use a warning app. This motivation is, in contrast, decreased when the messages are perceived as a disruption. While many oppose push notifications, favor finding persuasively designed preparedness advice in a separate menu or as an optional notification.},

Our approach is based on inexpensive and readily available microcontrollers with integrated LoRa hardware that we empower to receive and forward messages via Bluetooth, Wi-Fi, or a serial connection by means of a dedicated firmware, called rf95modem. The developed firmware cannot only be used in crisis scenarios but also in a variety of other applications, such as providing a communication fallback during outdoor activities, geolocation-based games or broadcasting of local information. We present two applications to show the benefits of our approach. First, we introduce a novel device-to-device LoRa chat application that works on both Android and iOS as well as on traditional computers like notebooks using a console-based interface. Second, we demonstrate how other infrastructure-less technology can benefit from our approach by integrating it into the DTN7 delay-tolerant networking software. Furthermore, we present the results of an in-depth experimental evaluation of approach consisting of (i) real-world device-to-device LoRa transmissions in urban and rural areas and (ii) scalability tests based on simulations of LoRa device-to-device usage in a medium-sized city with up to 1000 active users. The firmware, our device-to-device chat application, our integration into DTN7, as well as our code fragments of the experimental evaluation and the experimental results are available under permissive open-source licenses.},

abstract = {The use of social media today is not only ubiquitous and an integral part of everyday life but is also increasingly relevant before, during, or after emergencies. Data produced in these contexts, such as situational updates and multimedia content, is disseminated across different social media platforms and can be leveraged by various actors, including emergency services or volunteer communities. However, the dissemination of several thousand or even millions of messages during large-scale emergencies confronts analysts with challenges of information quality and overload. Hence, crisis informatics as a research domain seeks to explore and develop systems that support the collection, analysis, and dissemination of valuable social media information in emergencies. This chapter presents the social media API (SMA), which is a multi-platform service for gathering big social data across different social media channels and analyzing the credibility and relevance of collected data by the means of machine learning models. Based on the lessons learned from both the implementation process and user-centered evaluations in multiple emergency settings, this chapter discusses core challenges and potentials of the SMA and similar services, focusing on (1) the multi-platform gathering and management of data, (2) the mitigation of information overload by relevance assessment and message grouping, (3) the assessment of credibility and information quality, and (4) user-centered tailorability and adjustable data operations.},

Thus, Law Enforcement Agencies (LEA) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberabuse.

Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYLENCE project, which seeks to design strategies and tools for cross-media reporting, detection, and treatment of cyberbullying and hatespeech in investigative and law enforcement agencies. Second, it identifies and elaborates seven research challenges with regard to the monitoring, analysis and communication of cyberabuse in LEAs, which serve as a starting point for in-depth research within the project.},

abstract = {Publicly available information contains valuable information for Cyber Threat Intelligence (CTI). This can be used to prevent attacks that have already taken place on other systems. Ideally, only the initial attack succeeds and all subsequent ones are detected and stopped. But while there are different standards to exchange this information, a lot of it is shared in articles or blog posts in non-standardized ways. Manually scanning through multiple online portals and news pages to discover new threats and extracting them is a time-consuming task. To automize parts of this scanning process, multiple papers propose extractors that use Natural Language Processing (NLP) to extract Indicators of Compromise (IOCs) from documents. However, while this already solves the problem of extracting the information out of documents, the search for these documents is rarely considered. In this paper, a new focused crawler is proposed called ThreatCrawl, which uses Bidirectional Encoder Representations from Transformers (BERT)-based models to classify documents and adapt its crawling path dynamically. While ThreatCrawl has difficulties to classify the specific type of Open Source Intelligence (OSINT) named in texts, e.g., IOC content, it can successfully find relevant documents and modify its path accordingly. It yields harvest rates of up to 52\%, which are, to the best of our knowledge, better than the current state of the art.},

However, for this purpose, previous works only use the texts available in databases such as nvd. With this work, the publicly available web pages referenced in the nvd are analyzed and made available as sources of texts through web scraping. A dl based method for predicting the vector is implemented and evaluated. The present work provides a classification of the nvd’s reference texts based on the suitability and crawlability of their texts. While we identified the overall influence of the additional texts is negligible, we outperformed the state-of-the-art with our dl prediction models.},

Especially in rural areas, the recovery of public network infrastructure can take some time, so a dedicated communication channel would be advantageous. We explore the possibility of transforming commodity LoRaWAN gateways into meshed network nodes for a digital emergency communication channel. In order to obtain the required parameters, we collected farm locations in Germany with OpenStreetMap. Based on the assumptions of LoRa communication range and considering our use case requirements, connecting farm communities seems theoretically feasible in many areas of our data set. To further analyze our idea, we ran simulations of two common DTN routing protocols with different scenarios. A proof-of-concept implementation allows smaller messages to be transmitted using real hardware and demonstrates that a decentralized communications infrastructure based on commodity hardware is possible.},

Since previous work has focused on urban environments or has conducted simulations, this work aims to gather concrete knowledge on the transmission characteristics in rural environments. Extensive field studies with varying geographic conditions and comparative tests in urban environments were performed using two different hardware implementations. Overall, it was found that the collected values in rural areas are significantly lower than the theoretical values. Nevertheless, the results certify that LoRaWAN technology has a high range that cannot be achieved with other common technologies for emergency communications.},

In contrast, attributing the origin of such activities remains problematic. The ambiguity of digital data raises the problem of misinterpreting available information, increasing the risk of misinformed reactions and conflict escalation. In order to reduce this risk, this paper proposes a transparency system based on technologies which usually already exist for IT security measures that an accused actor in a specific incident can use to provide credible information which plausibly assures his non-involvement. The paper analyses the technical requirements, presents the technical concept and discusses the necessary adjustments to existing IT networks for its implementation. Intended as a measure for conflict de-escalation, the paper further discusses the limitations of this approach, especially with regard to technical limits as well as the political motivation and behavior of states.},

abstract = {Cyberspace, already a few decades old, has become a matter of course for most of us, part of our everyday life. At the same time, this space and the global infrastructure behind it are essential for our civilizations, the economy and administration, and thus an essential expression and lifeline of a globalized world. However, these developments also create vulnerabilities and thus, cyberspace is increasingly developing into an intelligence and military operational area – for the defense and security of states but also as a component of offensive military planning, visible in the creation of military cyber-departments and the integration of cyberspace into states' security and defense strategies. In order to contain and regulate the conflict and escalation potential of technology used by military forces, over the last decades, a complex tool set of transparency, de-escalation and arms control measures has been developed and proof-tested. Unfortunately, many of these established measures do not work for cyberspace due to its specific technical characteristics. Even more, the concept of what constitutes a weapon – an essential requirement for regulation – starts to blur for this domain. Against this background, this thesis aims to answer how measures for the de-escalation of state-led conflicts in cyberspace and arms control of cyberweapons can be developed. In order to answer this question, the dissertation takes a specifically technical perspective on these problems and the underlying political challenges of state behavior and international humanitarian law in cyberspace to identify starting points for technical measures of transparency, arms control and verification. Based on this approach of adopting already existing technical measures from other fields of computer science, the thesis will provide proof of concepts approaches for some mentioned challenges like a classification system for cyberweapons that is based on technical measurable features, an approach for the mutual reduction of vulnerability stockpiles and an approach to plausibly assure the non-involvement in a cyberconflict as a measure for de-escalation. All these initial approaches and the questions of how and by which measures arms control and conflict reduction can work for cyberspace are still quite new and subject to not too many debates. Indeed, the approach of deliberately self-restricting the capabilities of technology in order to serve a bigger goal, like the reduction of its destructive usage, is yet not very common for the engineering thinking of computer science. Therefore, this dissertation also aims to provide some impulses regarding the responsibility and creative options of computer science with a view to the peaceful development and use of cyberspace.},

abstract = {Cyberspace is a fragile construct threatened by malicious cyber operations of different actors, with vulnerabilities in IT hardware and software forming the basis for such activities, thus also posing a threat to global IT security. Advancements in the field of artificial intelligence accelerate this development, either with artificial intelligence enabled cyber weapons, automated cyber defense measures, or artificial intelligence-based threat and vulnerability detection. Especially state actors, with their long-term strategic security interests, often stockpile such knowledge of vulnerabilities and exploits to enable their military or intelligence service cyberspace operations. While treaties and regulations to limit these developments and to enhance global IT security by disclosing vulnerabilities are currently being discussed on the international level, these efforts are hindered by state concerns about the disclosure of unique knowledge and about giving up tactical advantages. This leads to a situation where multiple states are likely to stockpile at least some identical exploits, with technical measures to enable a depletion process for these stockpiles that preserve state secrecy interests and consider the special constraints of interacting states as well as the requirements within such environments being non-existent. This paper proposes such a privacy-preserving approach that allows multiple state parties to privately compare their stock of vulnerabilities and exploits to check for items that occur in multiple stockpiles without revealing them so that their disclosure can be considered. We call our system ExTRUST and show that it is scalable and can withstand several attack scenarios. Beyond the intergovernmental setting, ExTRUST can also be used for other zero-trust use cases, such as bug-bounty programs.},

This chapter seeks to supplement this effort by analyzing interaction, role, information, and perception patterns, which were prevalent in the past 20 years of social media use in crises.},

abstract = {The value of social media in crises, disasters, and emergencies across different events, participants, and states is now well-examined in crisis informatics research. Previous research has contributed to the state of the art with empirical insights on the use of social media, approaches for the gathering and processing of big social data, the design and evaluation of information systems, and the analysis of cumulative and longitudinal data. While some studies examined social media use representatively for their target audience, these usually only comprise a single point of inquiry and do not allow for a trend analysis. This work provides results (1) of a representative survey with German citizens from 2021 on use patterns, perceptions, and expectations regarding social media during emergencies. Furthermore, it (2) compares these results to previous surveys and provides insights on temporal changes and trends from 2017, over 2019 to 2021. Our findings highlight that social media use in emergencies increased in 2021 and 2019 compared to 2017. Between 2019 and 2021, the amount of information shared on social media remained on a similar level, while the perceived disadvantages of social media in emergencies significantly increased. In light of demographic variables, the results of the 2021 survey confirm previous findings, according to which older individuals (45+ years) use social media in emergencies less often than younger individuals (18-24 years). Furthermore, while the quicker availability of information was one of the reasons for social media use, especially the potential information overload was a key factor for not using social media in emergencies. The results are discussed in light of the dynamic nature of attitudes regarding social media in emergencies and the need to account for heterogeneity in user expectations to build trustworthy information ecosystems in social media.},

abstract = {The use of Open Source Intelligence (OSINT) to monitor and detect cybersecurity threats is gaining popularity among Cybersecurity Emergency or Incident Response Teams (CERTs/CSIRTs). They increasingly use semi-automated OSINT approaches when monitoring cyber threats for public infrastructure services and incident response. Most of the systems use publicly available data, often focusing on social media due to timely data for situational assessment. As indirect and affected stakeholders, the acceptance of OSINT systems by users, as well as the conditions which influence the acceptance, are relevant for the development of OSINT systems for cybersecurity. Therefore, as part of the ethical and social technology assessment, we conducted a survey (N=1,093), in which we asked participants about their acceptance of OSINT systems, their perceived need for open source surveillance, as well as their privacy behavior and concerns. Further, we tested if the awareness of OSINT is an interactive factor that affects other factors. Our results indicate that cyber threat perception and the perceived need for OSINT are positively related to acceptance, while privacy concerns are negatively related. The awareness of OSINT, however, has only shown effects on people with higher privacy concerns. Here, particularly high OSINT awareness and limited privacy concerns were associated with higher OSINT acceptance. Lastly, we provide implications for further research and the use of OSINT systems for cybersecurity by authorities. As OSINT is a framework rather than a single technology, approaches can be selected and combined to adhere to data minimization and anonymization as well as to leverage improvements in privacy-preserving computation and machine learning innovations. Regarding the use of OSINT, the results suggest to favor approaches that provide transparency to users regarding the use of the systems and the data they gather.},

url = {https://tuprints.ulb.tu-darmstadt.de/22849/},
abstract = {Technologies that can be used in military and civilian applications are referred to as dual-use. The dual-use nature of many information and communications technologies (ICTs) raises new questions for research and development for national, international, and human security. Measures to deal with the risks associated with the various dual-use technologies, including proliferation control, design approaches, and policy measures, vary widely. For example, Autonomous Weapon Systems (AWS) have not yet been regulated, while cryptographic products are subject to export and import controls. Innovations in artificial intelligence (AI), robotics, cybersecurity, and automated analysis of publicly available data raise new questions about their respective dual-use risks.
Dual-use risks have been systematically discussed so far, especially in the life sciences, which have contributed to the development of methods for assessment and risk management. Dual-use risks arise, among other things, from the fact that safety-critical technologies can be easily disseminated or modified, as well as used as part of a weapon system. Therefore, the development and adaptation of robots and software requires an independent consideration that builds on the insights of related dual-use discourses. Therefore, this dissertation considers the management of such risks in terms of the proliferation, regulation, and design of individual dual-use information technologies. Technology Assessment (TA) is the epistemological framework for this work, bringing together the concepts and approaches of Critical Security Studies (CSS) and Human-Computer Interaction (HCI) to help evaluate and shape dual-use technologies.
In order to identify the diffusion of dual-use at an early stage, the dissertation first examines the diffusion of dual-use innovations between civilian and military research in expert networks on LinkedIn, as well as on the basis of AI patents in a patent network. The results show low diffusion and tend to confirm existing studies on diffusion in patent networks. In the following section, the regulation of dual-use technologies is examined in the paper through two case studies. The first study uses a discourse analysis to show the value conflicts with regard to the regulation of autonomous weapons systems using the concept of Meaningful Human Control (MHC), while a second study, as a long-term comparative case study, analyzes the change and consequences of the regulation of strong cryptography in the U.S. as well as the programs of intelligence agencies for mass surveillance. Both cases point to the central role of private companies, both in the production of AWS and as intermediaries for the dissemination of encryption, as well as surveillance intermediaries. Subsequently, the dissertation examines the design of a dual-use technology using an Open Source Intelligence System (OSINT) for cybersecurity. For this purpose, conceptual, empirical, and technical studies are conducted as part of the Value-Sensitive Design (VSD) framework. During the studies, implications for research on and design of OSINT were identified. For example, the representative survey of the German population has shown that transparency of use while reducing mistrust is associated with higher acceptance of such systems. Additionally, it has been shown that data sparsity through the use of expert networks has many positive effects, not only improving the performance of the system, but is also preferable for legal and social reasons. Thus, the work contributes to the understanding of specific dual-use risks of AI, the regulation of AWS and cryptography, and the design of OSINT in cybersecurity. By combining concepts from CSS and participatory design methods in HCI, this work provides an interdisciplinary and multi-method contribution.},

In this paper, we investigate which values and value conflicts emerge due to the application and development of machine learning (ML) based OSINT technologies to assist cyber security incident response operators. For this purpose, we employ a triangulation of methods, consisting of a systematic survey of the technical literature on the development of OSINT artefacts for cybersecurity (N = 73) and an empirical value sensitive design case study, comprising semi-structured interviews with stakeholders (N = 9) as well as a focus group (N = 7) with developers.

abstract = {Like past crises, the COVID-19 pandemic has also activated individual volunteers to help to respond to the crisis. This includes digital volunteers, who have organized physical aid and conducted activities on social media. Analyzing German volunteering support groups on Facebook and related Reddit threads in the context of the COVID-19 pandemic, we {\textbackslash}updatedshow what type of help is offered and how social media users interact with each other, trying to cope with the situation. We reveal that most users offering help online conduct mostly typical care work, such as buying groceries or giving advice. Crucially, volunteering is characterized by relationships of care and thus builds on affirmative interactions. Albeit some misdirected offers and regressive interruptions, people use the possibility to make their voices heard and, showing empathy, help each other to cope with crisis. Social media like Facebook mediate societal structures, including relationships of care, offering a space for continuous, cumulatively resilient conduct of care work. Reflecting on the traditional division of labor in crisis volunteering and counter-productive dynamics of care and empathy, we aim for feminist ethics of care which allows for interactions on social media that foster generative computer-supported collaboration.},

Due to the practical relevance of HCI and disciplinary debates about human-centered design, this literature review studies HCI scholarships’ visions of military human-computer interaction. Through text analysis and categorization of publications, it is found that interaction is envisioned to take place in the context of both missionoriented operational (e.g., target detection) as well as organizational tasks (e.g., military training). While artificial intelligence, virtual/augmented reality, and robots are most frequently defined as technological environments, goals, such as situation awareness, enjoyment, and trust are predominantly associated with them. Considering scholarly references to application contexts and different factors of the context of use allows to systematically approach how military human-computer interaction is imagined. Offering insight into research trends in HCI, this first overview of research endeavors also contributes to interdisciplinary debates, such as Security Studies and technology assessment.},

Especially in crises or threatening situations, privacy may conflict with other values, such as personal safety and health. In other cases, personal or public safety can also be dependent on privacy: the context of flight shows how, for those affected, the value of data protection can increase as a result of an increased threat situation. Thus, when individual sovereignty—the autonomous development of one’s own will—or safety is highly dependent on information flows, people tend to be more protective of their privacy in order to maintain their information sovereignty. But also, the context of agriculture, as part of the critical infrastructure, shows how privacy concerns can affect the adoption of digital tools. With these two examples, flight and migration as well as agriculture, this chapter presents some exemplary results that illustrate the importance of the influence of situational factors on perceived information sovereignty and the evaluation of privacy.},

Users have minimal control over the software. Hence, it is very likely that the user misses that illegal recordings and transmissions occur if a security camera or a smart speaker is hacked. In this paper, we present SCAtt-man, the first remote attestation scheme that is specifically designed with the user in mind. SCAtt-man deploys software-based attestation to check the integrity of remote devices, allowing users to verify the integrity of IoT devices with their smartphones. The key novelty of SCAtt-man resides in the utilization of user-observable side-channels such as light or sound in the attestation protocol. Our proof-of-concept implementation targets a smart speaker and an attestation protocol that is based on a data-over-sound protocol. Our evaluation demonstrates the effectiveness of toolname against a variety of attacks and its usability based on a user study with 20 participants.},

To explore human-related challenges at the intersection of safety and security, we conducted three focus group workshops with N= 16 experts from both domains. We introduced two scenarios leading to a power outage, one with a safety-related cause (snow storm) and one with a security-related cause (cyber attack). The experts discussed interactions, differences and parallels in coping with the scenarios. Additionally, potential solutions for building response capacity by including volunteers were explored. The findings indicate similar consequences resulting from the safety- vs. security-related incidents. However, the experts identified relevant differences in the challenges preparing for and coping with the scenarios. While security-related challenges included the incalculable time horizon, impact and cascading effects as well as lack of emergency plans and training, safety challengesmainly concerned accessibility of the affected area.

abstract = {Im Forschungsprojekt " Das Netz hat Geschichte: Netzwerk- und Vulnerabilitätsanalyse Kritischer Infrastrukturen am Beispiel IKT und Verkehr in Rhein/Main”" wird das historische Wachstum von IKT- und Schieneninfrastrukturnetzen, sowie daraus erwachsene Konsequenzen für deren Vulnerabilitäten am Beispiel der Rhein-Main-Region interdisziplinär untersucht. Beide Infrastrukturnetze entstanden über Jahrzehnte hinweg und sind das Ergebnis verschiedener Interessen und technischer Entwicklungen aus unterschiedlichen Zeitschichten. Dies beeinflusst die Widerstandsfähigkeit der Netze und birgt potenzielle Risiken. Anhand von ca. 20 Expert:inneninterviews soll das Wissen von Praktiker:innen über das Alter, die Ausbreitung, technische Neuerungen und deren Auswirkungen analysiert werden. Die Forschung basiert auf dem Zeitschichtenmodell von Koselleck, das es ermöglicht, die verschiedenen zeitlichen Ebenen der Infrastrukturentwicklung zu analysieren. Die Ergebnisse der semi-strukturierten Interviewstudie zum impliziten Wissen der Befragten werden genutzt, um Hypothesen zu generieren, die später mittels Archivstudien und Netzwerkanalysen überprüft werden. Die gewonnenen Erkenntnisse können zur Stärkung der Resilienz von Infrastrukturen, insbesondere bei Katastrophenszenarien regionalen Ausmaßes, und zukünftigen Investitionsentscheidungen beitragen.},

In order to illustrate the current state of these trends, we further want to study an exemplary and very relevant application domain. According to Abdul et al.

abstract = {In many cases of machine learning, research suggests that the development of training data might have a higher relevance than the choice and modelling of classifiers themselves. Thus, data augmentation methods have been developed to improve classifiers by artificially created training data. In NLP, there is the challenge of establishing universal rules for text transformations which provide new linguistic patterns. In this paper, we present and evaluate a text generation method suitable to increase the performance of classifiers for long and short texts. We achieved promising improvements when evaluating short as well as long text tasks with the enhancement by our text generation method. Especially with regard to small data analytics, additive accuracy gains of up to 15.53\% and 3.56\% are achieved within a constructed low data regime, compared to the no augmentation baseline and another data augmentation technique. As the current track of these constructed regimes is not universally applicable, we also show major improvements in several real world low data tasks (up to +4.84 F1-score). Since we are evaluating the method from many perspectives (in total 11 datasets), we also observe situations where the method might not be suitable. We discuss implications and patterns for the successful application of our approach on different types of datasets.},

abstract = {Concise instruments to determine privacy personas – typical privacy-related user groups – are not available at present. Consequently, we aimed to identify them on a privacy knowledge–privacy behavior ratio based on a self-developed instrument. To achieve this, we conducted an item analysis (N = 820) and a confirmatory factor analysis (CFA) (N = 656) of data based on an online study with German participants. Starting with 81 items, we reduced those to an eleven-item questionnaire with the two scales privacy knowledge and privacy behavior. A subsequent cluster analysis (N = 656) revealed three distinct user groups: (1) Fundamentalists scoring high in privacy knowledge and behavior, (2) Pragmatists scoring average in privacy knowledge and behavior and (3) Unconcerned scoring low in privacy knowledge and behavior. In a closer inspection of the questionnaire, the CFAs supported the model with a close global fit based on RMSEA in a training and to a lesser extent in a cross-validation sample. Deficient local fit as well as validity and reliability coefficients well below generally accepted thresholds, however, revealed that the questionnaire in its current form cannot be considered a suitable measurement instrument for determining privacy personas. The results are discussed in terms of related persona conceptualizations, the importance of a methodologically sound investigation of corresponding privacy dimensions and our lessons learned.},

Um diese Thematik weiter zu untersuchen, wird in dieser Arbeit eine systematische Literaturrecherche durchgeführt, um Herausforderungen und Potenziale in der Adressierung der Klimakrise durch eine effiziente und nachhaltige Entwicklung des IKT-Sektors zu analysieren. Die dabei untersuchte Literatur beinhaltet Herausforderungen wie zum Beispiel den hohen Energie- und Materialverbrauch der IKT-Geräte und Datenzentren sowie die entstehenden Entsorgungskosten und das Konsumverhalten der Nutzer*innen. Deswegen sollten die Nutzer*innen mehr Informationen zur Wartung, zum Kauf gebrauchter Geräte, und zum Recyceln/Entsorgen erhalten. Die Analyse lieferte aber auch viele Potenziale. Durch IKT können Effizienzsteigerungen in den Bereich Industrie, Landwirtschaft, Verkehr und Transport erreicht und auch umweltschädliche Geräte substituiert werden. Durch diese Potenziale kann es aber, wie in anderen Bereichen, zu einem Rebound-Effekt kommen.},

Betrachtetwerden dafür die Themengebiete Anti-Patterns, Grey Patterns und Dark-Patterns. Anti-Patterns bezeichnen wiederkehrende Lösungen für ein Konzept eines User Interfaces, die trotz guter Intention ungewünschte Nebeneffekte oder Konsequenzen haben. Dark-Patterns dagegen stellen Designentscheidungen dar, die durch Täuschung oder Ausnutzung psychischen Drucks versuchen Nutzer*innen zu Handlungen zu verleiten, von denen die Ersteller*innen des Dark-Patterns mehr profitieren als die Anwender* innen. Der Begriff Grey Patterns wird in dieser Arbeit für alle Design Patterns genutzt, die sich nicht direkt zuordnen lassen. Da es bisher kaum vergleichendeWerke und keinen Konsens zu diesen Themengebieten gibt, ist das Ziel dieser Arbeit ein grundlegendes Modell aufzustellen. Dabei wird durch die Untersuchung bestehender Literatur eine zusammenfassende Taxonomie und ein Vorgehen zur Unterscheidung von Anti-Patterns und Dark-Patterns erarbeitet, die als Grundlage für weitere Arbeiten und zur Entwicklung von Gegenmaßnahmen genutzt werden können.},

abstract = {The backbone network of submarine communication cables (SCC) carries 98\% of international internet traffic. Coastal and island states strongly depend on this physical internet infrastructure to provide internet connectivity. Although about 100 SCC breakdowns of human or natural origin occur at yearly average, a literature review reveals that there is no approach to assess individual state vulnerability to SCC failure in global comparison. In this article, the global SCC network is modeled based on publicly available data. Besides the analysis of the global network properties, a focus is put on remaining bandwidth capacities in three different failure scenario simulations of SCC breakdowns. As a result, this study identifies 15 highly vulnerable states and overseas territories, and another 28 territories that are classified as partially vulnerable to SCC failures. Since economic market decisions shape the structure of the SCC network, an uneven distribution of redundancies and the resulting vulnerability of disadvantaged economies can be confirmed. Therefore, the study's findings may contribute to a better assessment of the necessity of preventive protection measures of critical telecommunication infrastructures in states and territories characterized by high and medium vulnerability.},

This article conducts a qualitative content analysis of content on Twitter concerning the conflict in the Jammu and Kashmir region. The tweets following the death of a popular militant, Burhan Wani, cover three different themes: (1) criticism of intellectuals, (2) Burhan Wani's impact on the conflict, and (3) tweets referring to the conflict itself. Generally, people use Twitter to make their own point of view clear to others and discredit the opposing party, at the same time tweets are reflecting the antagonism between the two parties to the conflict, India and Pakistan. The sample of tweets reflects the lack of awareness among people in the region regarding the motivations of the new generation of militancy emerging in Kashmir after 1990.},

abstract = {Organizations affected by a cyber-attack usually rely on external Cyber Incident Response (CIR) consultants to conduct investigations and mitigate the impact. These CIR consultants need to make critical decisions that could have major impact on their clients. This preliminary investigation aims to get a better understanding of CIR decision-making and answers the following questions: (1.) To what extent do experienced CIR consultants use a Recognition-Primed Decision (RPD) Making strategy during their work? (2.) What are the implications for cyber crisis management as well as for training and decision-making? To answer these questions, we conducted a literature review and interviewed six experienced CIR consultants using the Critical Decision Method. Our analysis reveals that CIR consultants recognize situations based on past experiences and apply a course of action that has worked effectively in the past. This course of action is mainly aimed at collecting and evaluating more data. This finding differs from other operational domains such as the military and fire department, where recognition is usually followed immediately by action. For cyber crisis management, this means that crisis management teams should decide to what extent and in what ways they want to mitigate the risk of responding belatedly to cyber events, which could potentially lead to unnecessary data theft and sustained business disruption. Another implication is that crisis management teams should consider whether additional forensic investigation outweighs the expected benefits throughout the response process. For instance, if the likely entry-point of the attacker has been discovered, how much effort should be devoted to exclude other potential entry-points. Reflecting on the status-quo, several implications for training and decision-making are provided.},

Taking inspiration from social anthropologist Ulf Hannerz (2004, p. 226), who compared journalists and anthropologists as “neighboring groups engaged in a somehow parallel pursuit,” this article explores what researchers may learn from practitioners who conduct research without being on-site. Fed by various practical journalists’ experiences, the article aims to investigate how information and communication technologies (ICTs) and digitally mediated methods, such as online search tools and social media, can be used to establish contacts and gain trust remotely. Here, the relevance of these methods for accessing a field in general goes beyond the limitations imposed during the COVID-19 pandemic and can be of interest to all those who face difficulties of field access of any kind. Ultimately, this article reflects on corresponding ethical challenges that may arise while conducting research remotely.},

One goal of digital research is to also capture marginal-ized voices. With emerging risks related to digital research, such as digital surveillance and social media monitoring by adversaries (e.g., the military in Myanmar), research needs to be more thoughtfully conducted. Considering research ethics, an evolving discrepancy between security measures and values of social jus-tice, such as accessibility and representation, appears as most data-secure applications are not used widely and offers such as “Free Basics” entice people to use rather data-unsecure applica-tions. Reflecting on this existing discrepancy in ethical require-ments, I illustrate challenges of the German research context re-lated to digitally conducted research focusing on overt conflictive social contexts.},

abstract = {The impact of the rapid technological change on peace and security continuously grows and becomes increasingly complex. Against the background of a quickly deteriorating security environment, the international conference SCIENCE · PEACE · SECURITY ’21 (RWTH Aachen University, 8-10 September 2021) examined the role of emerging technologies. The 60 speakers and 220 participants came from the natural, technical and social sciences. Diplomats and representatives from international organisations participated in the discussions. Topics included nuclear, chemical and biological arms control, autonomy in weapon systems, cybersecurity and the militarization of space among others.
The main outcome was that all of these issues could be more effectively addressed by new approaches to rigorous interdisciplinary research collaboration to create policy-relevant knowledge and by tightening the nexus between the scientist and policy communities. Both can only be achieved and sustained by funding novel structures that enable scientific-technical scholars to engage on these topics.
Key problems to be addressed by integrating natural, technical and social science perspectives include early risk assessment of potential dual-use research and technologies – especially in bio-security and epidemiology as well as IT and robotic research. Ways forward are the inclusion of norms into technology design as well as addressing questions of responsibility and standards. For military-usable technologies, entirely new regulatory approaches are necessary to prevent escalatory dynamics and to maintain accountability structures, moving from object-based to behaviour-based approaches.
Scientific-technical research contributes to peace and security in positive ways. A prominent example are nuclear verification techniques. While instruments to monitor nonproliferation and test ban commitments benefit from further improvement, many gaps on how to verify future arms control and disarmament agreements still exist and must be urgently closed.
The best cutting-edge scientific and academic expertise that is required for these complex research tasks is found in universities and other independent research institutes. Typically, however, decisionmakers draw knowledge from governmental institutions because of ease and existing connections. Therefore, efforts should be made to better connect the policy and academic communities. Communication between both can be improved by meeting on a regular basis and not only when advice on a specific issue is sought. This can foster more stable relationships and increase an understanding of each other.
Lastly, opportunities should be improved for the younger generation of scientists and technologists to engage with policymakers. It is crucial to educate and engage early-on the next generation of scientifically-literate policymakers and security-aware scientists.},

By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

abstract = {Warning and emergency apps are an integral part of crisis informatics and particularly relevant in countries that currently do not have cell broadcast, such as Germany. Previous studies have shown that such apps are regarded as relevant, but only around 16\% of German citizens used them in 2017 and 2019. With the COVID-19 pandemic and a devastating flash flood, Germany has recently experienced severe crisis-related losses. By comparing data from representative surveys from 2017, 2019 and 2021, this study investigates whether these events have changed the perceptions of warning apps and their usage patterns in Germany. The study shows that while multi-hazard emergency and warning apps have been easily surpassed in usage by COVID-19 contact tracing apps, the use of warning apps has also increased and the pandemic has added new desired features. While these have been little-used during the COVID-19 pandemic, especially non-users see smartphone messengers app channels as possible alternatives to warning apps. In addition, regional warning apps appear promising, possibly because they make choosing a warning app easier when there are several available on the market.},

Social media are often defined as a “group of internet-based applications […] that allow the creation and exchange of user-generated content” (Kaplan and Haenlein 2010). Shaping opinions, politics, participation, and protest (Wulf et al. 2013), they are used by citizens for news consumption and social exchange (Robinson et al. 2017); by journalists for reporting, analyzing, and collecting information (Stieglitz et al. 2018a); and by organizations to monitor crises, emergencies, customer feedback, and sentiment, among others (Haunschild et al. 2020). Large-scale international events, such as the 2010 Arab Spring, showcased the potential of socio-technological transformations: Citizens were not passive victims but active and autonomous participants utilizing social media to coordinate protest and for crisis response (Reuter and Kaufhold 2018). However, in other cases, citizens’ activities coordinated via social media also increased the complexity of tasks and pressure for formal authorities, since the lack of state control has not had only empowering or benign effects. Instead, on social media, false information spreads fast and it is easy for groups to find an audience there, either to enhance their profit or to target vulnerable groups with dangerous ideology.},

Using the lens of design science research, this paper contributes with the design and evaluation of a cross-platform cybersecurity dashboard for CERTs.

Furthermore, we asked what information and channels citizens need to be aware of cyber threats. Our findings indicate that large proportions of the German population feel inadequately informed about cyber threats and tend to only apply enforced security measures by programs (e.g., updates) and services (e.g., two-factor authentication). Furthermore, institutions such as state-level Computer Emergency Response Teams (CERTs) are relatively unknown among the population and respondents showed little confidence in German security authorities to cope with largescale attacks and ultimately protect citizens. Still, our participants prefer to receive cybersecurity information via installed security applications, television channels, or emergency warning apps.},

In a dynamic field like cybersecurity, gathering up-to-date information is usually a manual, time-consuming, and exhaustive task. Automatic and usable approaches are supposed to be a solution to this problem, but for this, they require a notion of information relevance to distinguish relevant from irrelevant information. First, on the basis of a literature review, this paper proposes a novel cybersecurity tool categorization based on corresponding tool types with their respective definitions and core features. Second, it elaborates information used in each category and deduces notions of relevance. Third, it outlines how these findings informed the design of a security dashboard to guide computer emergency response team staff in identifying current threats in open source intelligence sources while mitigating information overload.},

abstract = {Agriculture is subject to high demands regarding resilience as it is an essential component of the food production chain. In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur, such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers (N = 52) and a survey with participants from the agricultural sector (N = 118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture. The result is a low robustness capacity, as our analysis concludes with the risk of food production losses.},

abstract = {The Internet of Things (IoT) is a major trend that is seen as a great opportunity to improve efficiency in many domains, including agriculture. This technology could transform the sector, improving the management and quality of agricultural operations, for example, crop farming. The most promising data transmission standard for this domain seems to be Long Range Wide Area Network (LoRaWAN), a popular representative of low power wide area network technologies today. LoRaWAN, like any wireless protocol, has properties that can be exploited by attackers, which has been a topic of multiple research papers in recent years. By conducting a systematic literature review, we build a recent list of attacks, as well as collect mitigation options. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluate the practicality of both exploiting the vulnerabilities and implementing the countermeasures. We detected 16 attacks that we grouped into six attack types. Along with the attacks, we collect countermeasures for attack mitigation. Developers can use our findings to minimize the risks when developing applications based on LoRaWAN. These mostly theoretical security recommendations should encourage future works to evaluate the mitigations in practice.},

Since data are hardly controllable once they have been published or shared with others, it is highly important that users are clearly informed about who has access to which data and how certain settings can prevent the disclosure of sensitive data. However, giving end users more control over their data through increased transparency could also lead to information overload. This is particularly true in the field of agriculture, where tight schedules put pressure on employees of small enterprises. We conduct an empirical prestudy with 52 German farmers to investigate current data sharing scenarios. From these insights, we derive requirements and a concept for data sharing solutions providing data flow transparency for users. To investigate the behavior of users and the effects of transparent UI controls, we evaluate a prototype with 18 persons. Our evaluation shows that farmers demand flexible and secure tools that adjust to their workflows. Also, data should be stored and processed locally, granting farmers data sovereignty. Although the controls require additional effort, the evaluated transparent controls for data disclosure are easy to use and raise user awareness.},

Denn: Eine aktive Rüstungskontrollpolitik Deutschlands kann helfen, die Gefahren der weltweiten Aufrüstung und regionaler Rüstungs- und Eskalationsdynamiken zu mindern. Rüstungskontrollpolitische Instrumente müssen jede Vereinbarung über das Ende des Kriegs gegen die Ukraine stützen. Vereinbarungen über die Nichtverbreitung von Massenvernichtungswaffen bestimmen Regeln, die den militärischen Missbrauch von dual use-Technologien verhindern können. Abrüstung und Rüstungskontrolle mindern schon jetzt menschliches Leid in anderen Weltregionen. Abrüstung kann dazu beitragen, das vorherrschende und im Krieg gegen die Ukraine zunehmend unberechenbare Abschreckungsparadigma zu überwinden. Eine engagierte Rüstungskontrollpolitik fügt sich dann in die feministische Außenpolitik der Bundesregierung, wenn sie partizipativ und restriktiv angelegt ist und negative Folgen von Aufrüstung und Krieg besonders für Frauen und marginalisierte Gruppen reduziert.

In this paper, we analyzed these events in Germany in recent years and found out how they can be detected, and what impact they have on citizens, especially in crisis situations. For this purpose, we take a look at two different approaches to recording internet outages, namely the self-reporting of citizens and automatic reporting by algorithmic examination of the availability of IP networks. We evaluate the data of six major events with regard to their meaningfulness in quality and quantity. We found that due to the amount of data and the inherent imprecision of the methods used, it is difficult to detect outages through algorithmic examination. But once an event is publicly known by self-reporting, they have advantages to capture the temporal and spatial dimensions of the outage due to its nature of objective measurements. As a result, we propose that users’ crowdsourcing can enhance the detection of outages and should be seen as an important starting point to even begin an analysis with algorithm-based techniques, but it is to ISPs and regulatory authorities to support that.},

abstract = {Within CSCW and HCI, an increasing body of literature has been demonstrating the essential relevance of infrastructures and infrastructuring to the work of people engaging in technologically mediated nomadicity. Tech Nomads – or T-Nomads, as they are sometimes called – not only rely on technological, human, and environmental infrastructural components – such as Wi-Fi, technical support, space, and basic resources such as light and power outlets – but they also have to engage in infrastructuring to mobilise their workplaces and effectively accomplish work in and across different locations. In this article, we bring an infrastructuring perspective to understanding nomadic practices concerning the organisation of complex collaborative events. We introduce findings from a long-term investigation focusing on how infrastructures are re-instantiated with the help of digital technologies, according to emerging demands from T-Nomads. Our findings demonstrate the need for a ‘nonessentialist’ approach to nomadicity, one which recognises the character of nomadic work and its varied aspects in different contexts. We extend the infrastructuring literature by demonstrating how infrastructuring work is done in a complex collaborative initiative, as the organisation of the annual European Social Forum.},

abstract = {Technological and scientific progress, especially the rapid development of information technology (IT), plays a crucial role in peace and security issuesFootnote1. Artificial Intelligence (AI) is one example. AI is a sub-discipline of computer science, dealing with computer systems capable of performing tasks which require human intelligenceFootnote2. According to James Johnson, PhD, Lecturer in Strategic Studies in the Department of Politics \& International Relations at the University of Aberdeen and author of the book Artificial Intelligence and the Future of Warfare, the hype around this has made it easy to overstate the opportunities and challenges posed by the development and deployment of AI in the military sphere. The author argues, that “speculations about super intelligent AI or the threat of superman AI to humanity” are entirely disconnected from today’s capabilities of AI. The book aims to address this problem by deciphering “proven capabilities and applications from mere speculation”, with a strong focus on the challenges AI poses to strategic stability, nuclear deterrence and how AI might influence nuclear weapon systems. The author concludes with implications and policy recommendations on how states could manage the escalatory risks posed by AI.},

abstract = {The revelation of the Stuxnet malware in 2010 shed light on the presence of state actors that are willing and capable of developing and using highly sophisticated, specialized malicious software for their political interests. These tools -often dubbed cyber weapons -are expected to become the next major advancement in weaponry technology. Besides the threats of offensive cyber operations for civil IT systems due to the interconnected nature of the cyberspace, international regulation of cyber weapons is -among other aspects -hindered by the fact that the military development and the strategic and tactical deployment of cyber weapons differ significantly from other weapons technologies. In order to establish measures of cyber arms related control treaties, it is crucial to identify these particular characteristics. Based on this premise, the article analyzes the current perspectives on cyber weapons, identifying their weaknesses of being either based on assumptions about adversarial actors or being applicable only after the usage of a malicious tool. In contrast to these approaches, the article focuses on the specific functional aspects of malware and presents an indicator-based assessment model based on parameters that can be measured prior to the application of malicious software. This enables the categorization of malicious tools as cyber weapons. Besides this, the article aims to introduce thought-provoking impulses with regard to social responsibility in computer science.},

abstract = {In the last decades, research has shown that both technical solutions and user perceptions are important to improve security and privacy in the digital realm. The field of ‘usable security’ already started to emerge in the mid-90s, primarily focussed on password and email security. Later on, the research field of ”usable security and privacy” evolved and broadened the aim to design concepts and tools to assist users in enhancing their behaviour with regard to both privacy and security. Nevertheless, many user interventions are not as effective as desired. Because of highly diverse usage contexts, leading to different privacy and security requirements and not always to one-size-fits-all approaches, tailorability is necessary to address this issue. Furthermore, transparency is a crucial requirement, as providing comprehensible information may counter reactance towards security interventions. This article first provides a brief history of the research field in its first quarter-century and then highlights research on the transparency and tailorability of user interventions. Based on this, this article then presents six contributions with regard to (1) privacy concerns in times of COVID-19, (2) authentication on mobile devices, (3) GDPR-compliant data management, (4) privacy notices on websites, (5) data disclosure scenarios in agriculture, as well as (6) rights under data protection law and the concrete process should data subjects want to claim those rights. This article concludes with several research directions on user-centred transparency and tailorability.},

abstract = {Cryptography has become ubiquitous in communication technology and is considered a necessary part of information security. However, both the regulation to restrict access to cryptography, as well as practices to weaken or break encryption, are part of the States’ security policies. The United States (U.S.) regulate cryptography for export in international trade as a dual-use good. However, the regulation has been increasingly loosened and transferred to bilateral agreements with Information and Communication Technology companies. At the same time, the National Security Agency attempted to implement a government encryption standard to guarantee itself easier access to data, thus progressively expanding surveillance on non-U.S. citizens. In this paper, using comparative policy analysis, we examine the evolution of both security policies by tracing the historical development of U.S. regulation of cryptography as a dual-use good, and surveillance technologies, and practices used from the 1990s to today. We conclude that the impact of the dual-use regulation has affected the efficiency of surveillance technology, by loosening regulations only for mass communication services, thereby supporting the proliferation of surveillance intermediaries, while working on strategies to collaborate and exploit their coverage.},

abstract = {The European Union (EU) has undertaken policies which address the research and development of artificial intelligence (AI). In light of debates of technology assessment which focus on risks for humans and questions of control of AI, the EU has propagated an ethical, human-centred approach of the application of AI. It is important to identify how the EU envisions AI as this may guide emerging norms in AI governance and today’s research and development of (weaponised) AI. Building on works of Human-Computer Interaction (HCI), this work derives the actor’s understanding of human-AI interaction, including conceptualisations of explainability, interpretability, and risks. Analysis of EU documents on the implementation of AI as a general-purpose technology and for military application reveals that explainability and risk identification are crucial elements for trust, which itself is a necessary component in the uptake of AI. Interdisciplinary approaches allow for a more detailed understanding of actors’ fundamental views on human control of AI, which further contributes to debates on technology assessment in professionalised political contexts.},

abstract = {Artificial Intelligence (AI) seems to be impacting all industry sectors, while becoming a motor for innovation. The diffusion of AI from the civilian sector to the defense sector, and AI’s dual-use potential has drawn attention from security and ethics scholars. With the publication of the ethical guideline Trustworthy AI by the European Union (EU), normative questions on the application of AI have been further evaluated. In order to draw conclusions on Trustworthy AI as a point of reference for responsible research and development (R\&D), we approach the diffusion of AI across both civilian and military spheres in the EU. We capture the extent of technological diffusion and derive European and German patent citation networks. Both networks indicate a low degree of diffusion of AI between civilian and defense sectors. A qualitative investigation of project descriptions of a research institute’s work in both civilian and military fields shows that military AI applications stress accuracy or robustness, while civilian AI reflects a focus on human-centric values. Our work represents a first approach by linking processes of technology diffusion with normative evaluations of R\&D.},

abstract = {In the digital age, the vision of autonomous vehicles (AVs) is vibrant. Research is being conducted worldwide to inte-grate AVs into our everyday lives in the future, spending consid-erable amounts of money in the development process. Actors from both engineering as well as social sciences are involved in this re-search, with technical disciplines strongly dominating. In addition to perceived progress of numerous newly developed technologies such as AVs, challenges should also be referred to. According to research analysis, the transferability of autonomous cars to the military sphere seems to be frequently forgotten or ignored (dual-use). Since not much research has been conducted in Germany on the potential deployment of autonomous driving development steps into military domains, 25 semi-structured interviews with de-velopers and researchers and actors involved in the field, were conducted in 2020. The paper identifies that the majority of re-spondents interviewed were aware of general existing dual-use de-bates, however, few had reflected about dual-use issues regarding a possible transfer of their own development processes in the con-text of autonomous driving to military applications, intensively. One reason is the small-scale nature of research, another is the complexity of the field, which enables the engineer’s alienation from their responsibility for the artefacts’ use. Moreover, it has become clear that hardly any conversations among colleagues oc-cur about possible misuse and that no standardized policy guide-lines exist, which provide information about possible risk. To raise dual-use awareness, scientific contributions, risk education, and interdisciplinary discussions are essential.},

abstract = {In 1987, Allan Din published the seminal book “Arms and Artificial Intelligence,” in which he argued that the future military use of AI would be a double-edged sword. Warning about control failures and accidental war on one hand, Din also pointed out the potential of AI to enhance arms control. 35 years later, what was a niche technology in Din’s day has since become one of the most influential technologies in both the civilian and military sectors. In addition, AI has evolved from sophisticated yet deterministic expert systems to machine learning algorithms. Today, AI is about to be introduced in almost every branch of the military, with a variety of implications for arms control. This book reflects the work of the individual authors and identifies common themes and areas where AI can be used for the greater good or where its use calls for particular vigilance. It offers an essential primer for interested readers, while also encouraging experts from the arms control community to dig more deeply into the issues.},

abstract = {Looking at a variety of armament sectors, the book examines how Artificial Intelligence (AI) impacts the fields of armament and arms control, how existing arms control measures will be affected by AI, and what new approaches based on AI have been or are currently developed.
The significant increase in computing power, the increasing reliance on software, and the advent of (narrow) AI and deep-learning algorithms all have the potential to lead to disruptive changes for military operations and warfare, rendering many classical arms control instruments less effective, or even useless. On the other hand, AI might lead to completely new arms control approaches, raising the effectiveness and reliability of new verification measures. To provide a common understanding, the book starts by presenting a general introduction to the state of the art in artificial intelligence and arms control, and how the two topics are interrelated. The second part of the book looks at examples from various fields of weapon technology, including weapons of mass destruction (WMD), conventional armament, and emerging technologies. The final section offers a cross-cutting perspective based on the examples presented in the second part.
This volume will appeal to students and scholars of international relations, as well as policy-makers and practitioners interested in a better understanding of peace and security studies in general, and armament and arms control in particular with a strong focus on AI.},

abstract = {Past studies in the domains of information systems have analysed the potentials and barriers of social media in emergencies. While information disseminated in social media can lead to valuable insights, emergency services and researchers face the challenge of information overload as data quickly exceeds the manageable amount. We propose an embedding-based clustering approach and a method for the automated labelling of clusters. Given that the clustering quality is highly dependent on embeddings, we evaluate 19 embedding models with respect to time, internal cluster quality, and language invariance. The results show that it may be sensible to use embedding models that were already trained on other crisis datasets. However, one must ensure that the training data generalizes enough, so that the clustering can adapt to new situations. Confirming this, we found out that some embeddings were not able to perform as well on a German dataset as on an English dataset.},

However, the exact relationship between privacy and security behavior is rarely discussed in the literature. This study investigates this relationship and the role of socio-demographic factors (gender, age, education, political opinions) in such behavior. Exploratory results of a survey of German private users (N=1,219) show that privacy and security behavior are only weakly correlated and not similarly influenced by socio-demographic factors. While se-curity behavior significantly differs between age and education groups (younger and less educated show less security behavior), no such differences exist for pri-vacy behavior. Additionally, political orientation and opinion has no influence on privacy and security behavior. Thus, this study sheds light on the concepts of privacy, security and corresponding behavior and emphasizes the need for a fine-grained differentiation if either privacy or security behavior is to be improved.},

abstract = {Smart cities aim at improving efficiency while providing safety and security by merging conventional infrastructures with information and communication technology. One strategy for mitigating hazardous situations and improving the overall resilience of the system is to involve citizens. For instance, smart grids involve prosumers - capable of producing and consuming electricity - who can adjust their electricity profile dynamically (i.e., decrease or increase electricity consumption), or use their local production to supply electricity to the grid. This mitigates the impact of peak-consumption periods on the grid and makes it easier for operators to control the grid. This involvement of prosumers is accompanied by numerous socio-technical challenges, including motivating citizens to contribute by adjusting their electricity consumption to the requirements of the energy grid. Towards this end, this work investigates motivational strategies and tools, including nudging, persuasive technologies, and incentives, that can be leveraged to increase the motivation of citizens. We discuss long-term and side effects and ethical and privacy considerations, before portraying bug bounty programs, gamification and apps as technologies and strategies to communicate the motivational strategies to citizens.},

However, user-oriented phishing interventions are fragmented

overview of the various approaches taken by prior works.
In this paper, we present a taxonomy of phishing interventions
based on a systematic literature analysis. We shed light
on the diversity of existing approaches by analyzing them
with respect to the intervention type, the addressed phishing
attack vector, the time at which the intervention takes place,
and the required user interaction. Furthermore, we highlight
shortcomings and challenges emerging from both our literature
sample and prior meta-analyses, and discuss them in
the light of current movements in the field of usable security.
With this article, we hope to provide useful directions for
future works on phishing interventions.},

In other contexts, such as the health sector, studies have already thoroughly explored the attitude towards nudging. To address that matter in cybersecurity, we conducted a representative study in Germany (𝑁 = 1, 012), asking people about their attitude towards nudging in that specific context.

In this study, we conduct a representative survey of the German population to investigate personal experiences with and attitudes towards the police and information and communication technologies (ICT) used for policing.

Bisher ist allerdings nicht klar, was typische Beteiligungsformate von Smart-City-Initiativen sind und welche Rolle(n) BürgerInnen dabei einnehmen. Dieser Beitrag leitet mittels einer Literaturanalyse zu Smart Cities ein Kategorienschema zu typischen Bürgerbeteiligungsarten ab. Die Analyse ergab, dass sich Einbindung von BürgerInnen in politische Entscheidungen und bei der Entwicklung technischer Artefakte maßgeblich auf e‑Government oder Participatory Design bezieht. Im Hinblick auf die Beteiligungsarten zeigt sich, dass Makrofabriken, Living Labs und Open-Data-Plattformen häufige Ansätze sind, um BürgerInnen als Co-Creators einzubinden. Zudem werden BürgerInnen mit Citizen Sensing zur Erfassung von Daten oder Missständen einbezogen. Dabei zeigen sich sowohl aktivere, als auch eher passive Beteiligungsarten. Die Analyse zeigt, dass die Einbindung von BürgerInnen häufig entweder auf eine Beteiligung an politischen Entscheidungen oder an der Entwicklung technischer Artefakte abzielt. Auch wenn keine klare Abgrenzung möglich ist, sind diese Ansätze dann eher durch e‑Government oder Participatory Design inspiriert.},

Are people aware of the data they are sharing? What kind of data do people want to share with whom? Are people aware if they have Wi-Fi, GPS, or Bluetooth activated as potential data sharing functionalities on their phone? To answer these questions, we conducted a representative online survey as well as face-to-face interviews with users in Germany. We found that most users wanted to share private data on premise with most entities, indicating that willingness to share data depends on who has access to the data. Almost half of the participants would be more willing to share data with specific entities (state bodies \& rescue forces) in the event that an acquaintance is endangered. For Wi-Fi and GPS the frequencies of self-reported and actual activation on the smartphone are almost equal, but 17\% of participants were unaware of the Bluetooth status on their smartphone. Our research is therefore in line with other studies suggesting relatively low privacy awareness of users.},

abstract = {Despite the merits of digitisation in private and professional spaces, critical infrastructures and societies are increasingly ex-posed to cyberattacks. Thus, Computer Emergency Response Teams (CERTs) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberattacks. However, their tasks are getting more complex by the increasing amount and varying quality of information dissem-inated into public channels. Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYWARN project, which seeks to design strategies and technolo-gies for cross-platform cyber situational awareness and actor-spe-cific cyber threat communication. Second, it identifies and elabo-rates eight research challenges with regard to the monitoring, analysis and communication of cyber threats in CERTs, which serve as a starting point for in-depth research within the project.},

abstract = {Social media have an enormous impact on modern life but are prone to the dissemination of false information. In several domains, such as crisis management or political communication, it is of utmost importance to detect false and to promote credible information. Although educational measures might help individuals to detect false information, the sheer volume of social big data, which sometimes need to be anal- ysed under time-critical constraints, calls for automated and (near) real- time assessment methods. Hence, this paper reviews existing approaches before designing and evaluating three deep learning models (MLP, RNN, BERT) for real-time credibility assessment using the example of Twitter posts. While our BERT implementation achieved best results with an accuracy of up to 87.07\% and an F1 score of 0.8764 when using meta- data, text, and user features, MLP and RNN showed lower classification quality but better performance for real-time application. Furthermore, the paper contributes with a novel dataset for credibility assessment.},

Previous work has shown that machine readable information is either missing, incorrect, or inconsistent with other data sources. In this paper, we introduce a system called Overt Vulnerability source ANAlysis (OVANA), utilizing state-of-the-art machine learning (ML) and natural-language processing (NLP) techniques, which analyzes the information quality (IQ) of vulnerability databases, searches the free-form description for relevant information missing from structured fields, and updates it accordingly. Our paper shows that OVANA is able to improve the IQ of the National Vulnerability Database by 51.23\% based on the indicators of accuracy, completeness, and uniqueness. Moreover, we present information which should be incorporated into the structured fields to increase the uniqueness of vulnerability entries and improve the discriminability of different vulnerability entries. The identified information from OVANA enables a more targeted vulnerability search and provides guidance for IT security experts in finding relevant information in vulnerability descriptions for severity assessment.},

For example, if a farmer is in the field during a network outage, such as a failure of the mobile network, an alternative communication channel is needed to continue to connect to IT components and required data. With increasing digitalization, Low Power Wide Area Network (LPWAN) technologies are being used more and more frequently, e.g. for sensor networks. The LPWAN technologies offer a high range and can be used autonomously for the most part, but do not allow classic TCP/IP communication. In this work, a popular LPWAN technology, namely LoRaWAN, is experimentally supplemented by AX.25 on OSI layer 2 (Data Link Layer) to allow end devices TCP/IP-based communication over long distances. The evaluation shows that classic low-bandwidth applications are thus functional and can enable reliable, crisis-capable data transmission.},

Sollte sich ein Landwirt beispielsweise während eines lokalen Krisenfalls, wie einem Ausfall des Mobilfunknetzes oder des Internetzugangs des Betriebs, auf dem Feld aufhalten, wird ein alternativer Kommunikationskanal benötigt, um weiterhin eine Verbindung zu IT-Komponenten und benötigten Daten herstellen zu können. Mit der zunehmenden Digitalisierung finden Low-Power-Wide-Area-Network (LPWAN)-Technologien immer häufiger Anwendung, beispielsweise durch den Aufbau von Sensornetzwerken. Die eingesetzten LPWANTechnologien bieten dabei eine hohe Reichweite und sind größtenteils autark einsetzbar, erlauben jedoch keine klassische TCP/IP-Kommunikation.

abstract = {Technological progress can disrupt domains
and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

abstract = {Information and communication technologies affect all areas of civil society. Digitalization opens up new opportunities to address important social issues. The motor of digitalization can be social necessity, technical feasibility, and also a crisis, as the reaction to the COVID-19 pandemic demonstrates: Out of necessity, ideas are created, systems designed and implemented and the value of digital solutions to society becomes apparent. With the digitalization of everyday working and learning, apps for tracing information chains and containing new infections have potential, but also pose social risks. The current COVID-19 crisis seems to put the role of digitalization in a completely new light. Both, to evaluate the value of digital solutions to society and to identify space for innovation is important in times of intense digitalization efforts.
To meet the societal challenges posed by digitalization, it is particularly important to understand how they arise. The use of digital solutions in safety-critical contexts entails dependencies and the threat of various dangers: Infrastructure disruptions and failures can be caused by criminal acts, terrorist attacks, natural disasters, operational disruptions, and system failures. In addition, there is a concern about data arising from the use of digital solutions. Data protection, data sovereignty, data security, and their social perception must always be closely observed. Furthermore, it is important to ensure that digitalization does not lead to a digital divide. New digital solutions require constant evaluation and assessment of the consequences.},

abstract = {Kooperationstechnologien spielen in sicherheitskritischen Systemen eine große Rolle, da in vielen Anwendungsfeldern nicht nur die Interaktion von Mensch und Computer, sondern auch die durch IT unterstützte Kooperation zwischen Menschen notwendig ist, um Aufgaben bewältigen zu können. Solche Technologien müssen verschiedene Anfor-derungen erfüllen und können ebenfalls zur Resilienz beitragen. Unter Resilienz durch Kooperation verstehen wir die Fähigkeit, Krisen durch die Anpassungsfähigkeit an ge-änderte Realitäten ohne nachhaltigen Schaden mithilfe von Kooperation zu überstehen. Während das Konzept der Resilienz in den Ingenieurwissenschaften vornehmlich die Verfügbarkeit technischer Systeme fokussiert, betrachten wir Resilienz als soziotechni-sches Konstrukt, unter expliziter Betrachtung der beteiligten Akteur*innen. Basierend auf Grundlagen zu Kooperationstechnologien zeigt dieses Kapitel anhand von prakti-schen exemplarisch umgesetzten Kooperationstechnologien (soziales Netzwerk, GIS-System, Smartphone Apps, Facebook App und Social Media Analytics-Plattform), wie Kooperation unterstützt wird und zu kooperativer Resilienz beitragen kann.},

abstract = {Besides the merits of increasing digitization and interconnectedness in private and professional spaces, critical infrastructures and societies are more and more exposed to cyberattacks. In order to enhance the preventative and reactive capabilities against cyberattacks, Computer Emergency Response Teams (CERTs) are deployed in many countries and organizations. In Germany, CERTs in the public sector operate on federal and state level to provide information security services for authorities, citizens, and enterprises. Their tasks of monitoring, analyzing, and communicating threats and incidents is getting more complex due to the increasing amount of information disseminated into public channels. By adopting the perspectives of Computer-Supported Cooperative Work (CSCW) and Crisis Informatics, we contribute to the study of organizational structures, technology use, and the impact on collaborative practices in and between state CERTs with empirical research based on expert interviews with representatives of German state CERTs (N=15) and supplementary document analyses (N=25). We derive design and policy implications from our findings, including the need for interoperable and modular architecture, a shift towards service level agreements, cross-platform monitoring and analysis of incident data, use of deduplication techniques and standardized threat exchange formats, a reduction of resource costs through process automation, and transparent reporting and tool structures for information exchange.},

abstract = {Receiving relevant information on possible cyber threats, attacks, and data breaches in a timely manner is crucial for early response. The social media platform Twitter hosts an active cyber security community. Their activities are often monitored manually by security experts, such as Computer Emergency Response Teams (CERTs). We thus propose a Twitter-based alert generation system that issues alerts to a system operator as soon as new relevant cyber security related topics emerge. Thereby, our system allows us to monitor user accounts with significantly less workload. Our system applies a supervised classifier, based on active learning, that detects tweets containing relevant information. The results indicate that uncertainty sampling can reduce the amount of manual relevance classification effort and enhance the classifier performance substantially compared to random sampling. Our approach reduces the number of accounts and tweets that are needed for the classifier training, thus making the tool easily and rapidly adaptable to the specific context while also supporting data minimization for Open Source Intelligence (OSINT). Relevant tweets are clustered by a greedy stream clustering algorithm in order to identify significant events. The proposed system is able to work near real-time within the required 15-minutes time frame and detects up to 93.8\% of relevant events with a false alert rate of 14.81\%.},

One prominent approach for measuring spillover effects is based on the analysis of patent citation networks. Taking social media analytics and knowledge economics into account, this paper presents a complementary approach to quantify spillover effects from defense to civilian research and development, analyzing 513 employment biographies from the social network LinkedIn. Using descriptive network analysis, we investigate the emigration of personnel of the German defense industry to other civilian producers. Thereby, our study reveals that in the last decade, employees of defense suppliers have changed positions significantly less often, with 3.24 changes on average than professionals who have worked more than 50\% of their jobs in the civilian sector, having changed 4.61 times on average. Our work illustrates the churn behavior and how spillover effects between defense and civilian sectors can be measured using social career networks such as LinkedIn.},

abstract = {Since 2015, an increased number of asylum seekers is coming to Europe. These migration movements increasingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach their targeted destination countries. Asylum seekers often use smartphones for information and communication purposes. Even though there are many positive aspects in the use of such technologies, researchers have to consider the perceived risks of this specific user group. This work aims at investigating the use of mobile information technologies by asylum seekers during their flight, especially taking privacy into account. Thus, it examines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conducting a qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results show that asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, such as surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this, this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy and trust leads to avoidance behavior, the insights of this study provide valuable information for the design of assistance apps and collaboration platforms, which appropriately address the specific needs for digital privacy in the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.},

Aus der Perspektive materialistischer Staatskritik argumentieren wir erstens, dass die Auflösung der Seebrücken-Demonstration durch die Frankfurter Polizei im April 2020 als ein kurzes Aufblitzen und Einüben des Ausnahmestaats im Normalstaat zu verstehen ist, bei dem die Polizei ihren erweiterten Ermessenspielraum ausreizte. Zweitens ließ sich in den darauffolgenden Wochen beobachten, dass die rechten sogenannten „Hygienedemos“ weniger repressiv als progressive Versammlungen poliziert wurden. Dies führen wir auf die extremismusideologische behördliche Deutung der Proteste zurück, die nicht nur blind ist für Autoritarismus durch Staatsapparate, sondern damit einhergehend systematisch die extreme Rechte verharmlost.},

Three months after the event, we present an exemplifying analysis of the topics, used technologies and remaining activity of these projects. Shedding light on this instance of citizen science allows to highlight the potential of hackathons and startup culture regarding socio-technological resilience. At the same time, it may be understood as an impulse for crisis informatics to consider new forms of volunteering in the course of crisis management.},

Basing our questionnaire on a workshop with police officers, we present the results of a representative study on citizens' perception of social media in emergencies that we conducted in Germany. Our study suggests that when it comes to emergencies, socio-demographic differences are largely insignificant and no clear preferences for emergency services' social media strategies exist. Due to the widespread searching behavior on some platforms, emergency services can reach a wide audience by turning to certain channels but should account for groups with distinct preferences.},

Additionally, we ana- lyze the role of socio-demographic factors (gender, age, education, political ori- entation) for security knowledge and behavior. Results show that German pri- vate users have only moderate IT security knowledge and behavior, with as- pects as gender, age, education and political orientation partly having an influ- ence. Men, higher educated and politically moderately oriented participants show higher security knowledge, whereas young people and those less knowl- edgeable about security behave less security-conscious. Additionally, security knowledge and behavior correlate moderately. Therefore, to increase private users' IT security we suggest to increase education and training especially for users being young, politically right-wing or female.},
