Reflection, Education, Consistency: Towards Best Ethics Practices At Security And Privacy Conferences

Research ethics is a controversial and emotionally charged topic in the security and privacy community, sparking discussions at conferences and on social media. In recent years, some of the leading conferences have introduced interventions such as mandatory ethics sections, with mixed reactions within the community. Program committee chairs and steering committees increasingly emphasize ethics, yet there is limited empirical validation on ethics procedures and interventions, as well as no explicitly communicated goals. To support a shared understanding in our community and guide informed decisions at the conference level, we examined past ethics policies at the top-four conferences and conducted in-depth semi-structured interviews with senior and junior (n=20) community members, including some (former) chairs of program and research ethics committees. In these, we explored reasons for and goals of ethics procedures and discussed existing ethics interventions as well as possible new approaches proposed by our team. While the community appears to be evolving toward the identified goals, i.e., raising ethical awareness and preventing the publication of unethical work, we identified the lack of ethical education within the community itself as a major obstacle to further progress on this matter. Ethical education is often passed to the universities. Interviewees also mentioned challenges with the complexity of ethics policies and the lack of consistency across different conferences, as well as policies changing year-to-year. Several participants warned that over-regulation may lead to backlash, encouraging mere compliance, such as people turning to LLMs for ethics sections rather than undertaking in-depth consideration. In response, we suggest a coordinated, community-wide ethics steering effort and take a first step by introducing an open ethics wiki.

Web Execution Bundles: Reproducible, Accurate, and Archivable Web Measurements

Recently, reproducibility has become a cornerstone in the security and privacy research community, including artifact evaluations and even a new symposium topic. However, Web measurements lack tools that can be reused across many measurement tasks without modification, while being robust to circumvention, and accurate across the wide range of behaviors in the Web. As a result, most measurement studies use custom tools and varied archival formats, each of unknown correctness and significant limitations, systematically affecting the research's accuracy and reproducibility. To address these limitations, we present WebREC, a Web measurement tool that is, compared against the current state-of-the-art, accurate (i.e., correctly measures and attributes events not possible with existing tools), general (i.e., reusable without modification for a broad range of measurement tasks), and comprehensive (i.e., handling events from all relevant browser behaviors). We also present .web, an archival format for the accurate and reproducible measurement of a wide range of website behaviors. We empirically evaluate WebREC's accuracy by replicating well-known Web measurement studies and showing that WebREC's results more accurately match our baseline. We then assess if WebREC and .web succeed as general-purpose tools, which could be used to accomplish many Web measurement tasks without modification. We find that this is so: 70% of papers discussed in a 2024 web crawling SoK paper could be conducted using WebREC as is, and a larger number (48%) could be leveraged against .web archives without requiring any new crawling.

From Blocking to Breaking: Evaluating the Impact of Adblockers on Web Usability

Recent years have seen a sharp rise in adblocker use, driven by increased web tracking and personalized ads. However, a significant issue for adblocker users is the web breakages they encounter, which worsens their browsing experience and often leads them to turn off their adblockers. Despite efforts by filter list maintainers to create rules that minimize these breakages, they remain a common issue. Our research aims to assess the extent of web breakages caused by adblocking on live sites using automated tools, attempting to establish a baseline for these disruptions. The study also outlines the challenges and limitations encountered when measuring web breakages in real-time. The current automated crawler's inability to consistently navigate a vast array of websites, combined with the unpredictable nature of web content, makes this research particularly difficult. We have identified several key findings related to web breakages in our preliminary study, which we intend to delve deeper into in future research.
