Explore a groundbreaking keynote presentation that challenges the traditional approach to cybersecurity by examining why the same types of bugs persistently reappear across different systems and contexts. Delivered by Falcon Darkstar Momot from Dartmouth College at the USENIX Workshop on Offensive Technologies (WOOT '25), this 48-minute talk proposes shifting focus from individual bugs to understanding and eliminating entire bug classes. Learn how returning to fundamental formal computing principles can reveal the root causes of recurring security vulnerabilities and discover a framework-in-progress for categorizing meta-classes of bugs. Gain insights into how Language-theoretic Security (LangSec) perspectives offer unique pathways to break free from the endless cycle of finding and fixing the same types of security issues, ultimately moving beyond reactive security measures toward more systematic prevention strategies.
