PhD Candidate

Biography

I am currently a third-year Ph.D. candidate advised by Professor Nick Nikiforakis at the PragSec Lab in Stony Brook University. I investigate (the lack of) web integrity in various contexts (e.g., domain names and JavaScript) through large-scale experiments, and subsequently design and evaluate defenses that improve the integrity of the web.

Projects:

  • Designing a link management system that will enable administrators to manage all external resource dependencies of their websites and be notified of changes (ongoing)
  • Demonstrated that strict integrity verification of scripts cannot adequately protect the web through a large-scale, data-driven analysis (under submission)
  • Profiled the behavior of bots that monitor Certificate Transparency logs, analyzing how bots of various intentions and origins react to new certificates within seconds (Uninvited Guests)
  • Illustrated the capability of adversaries to potentially affect millions of IP addresses in tens of thousands of autonomous systems by re-registering a few hundred domains (Domains Change)
  • Proposed and evaluated deceptive web authentication mechanisms that remove the integrity of a web application from the attacker’s arsenal, and instead place the lack of it in the defender’s arsenal (Click This, Not That)
