Defining and Fortifying Against Cognitive Vulnerabilities in Social Engineering (Dagstuhl Seminar 23462)

Social engineering has become the main vector for human-centered cyber attacks, resulting from an unparalleled level of professionalization in the cybercrime industry over the past years. Hereby, through manipulation, criminals seek to make victims take actions that compromise security, such as revealing credentials, issuing payments, or disclosing confidential information. Little effective means for protection exist today against such attacks beyond raising awareness through education. At the same time, the proliferation of sensors in our everyday lives - both in personal devices and in our (smart) environments - provides an unprecedented opportunity for developing solutions assessing the cognitive vulnerabilities of users and serves as a basis for novel means of protection. This report documents the program and the outcomes of the Dagstuhl Seminar 23462 "Defining and Fortifying Against Cognitive Vulnerabilities in Social Engineering". This 3-day seminar brought together experts from academia, industry, and the authorities working on social engineering. During the seminar, participants developed a common understanding of social engineering, identified grand challenges, worked on a research agenda, and identified ideas for collaborations in the form of research projects and joint initiatives.
