I am a tenure-track faculty at CISPA Helmholtz Center for Information Security. With my group, we research on multiple aspects of the security of modern web applications.

Areas of interest:

  • Web security, security testing, and automated vulnerability analysis
  • ML/AI for security testing

Flash news : The Secure Web Development lecture and competition will take place this summer term!

Research

Current interests

Vulnerability Detection and Analysis:

  • Web application scanners (Black Widow [IEEE SP 2021], jAEk [RAID 2015])
  • Cross-site request forgery (Same-site Cookies [Oakland 2022], client-side CSRF detection (JAW) [Usenix 2021], the state of CSRF defenses implementations [RAID 2021], CSRF detection (Deemon) [ACM CSS 2017])
  • Server-side requests (Link previews [NDSS 2020], SSR abuse [RAID 2016])
  • Backdoors and hidden features [IEEE SP 2020]
  • Web API security [NDSS 2019]
  • Logic vulnerabilities [NDSS 2014]

Web Platform Security:

  • Web enclaves and trusted user I/O path (Fidelius [IEEE SP 2019])
  • Internet core services security (Who controls the Internet [WWW 2017], the Great Cannon [WOOT 2015])

Security of ML-based Systems:

  • Attacking perceptual ad-blocking [CCS 2019]
  • Detection of adversarial physical attacks [IEEE DLS 2020]
