Franzisca Roesner (University of Washington)

Online advertisements are an unavoidable fact of the modern web: they are embedded in and financially support the majority of content websites. Significant prior work in the computer security and privacy community has previously studied the ecosystem of online advertising, particularly in terms of its privacy implications. What has not been substantively considered in the security community, however, is the visible, user-facing content of these advertisements. Our recent work reveals significant prevalence of a range of problematic content in these ads, including clickbait, misinformation, scams, and manipulative design patterns. In this talk, I will describe our work characterizing and measuring problematic content in the online ad ecosystem, including an investigation of ad content on misinformation sites and a study of political-themed ads on news and media websites around the time of the 2020 U.S. elections.
