SAINTCON 2025 · Day 2 · Main Track 2
In "Give me the Green Light: An Intro to Hacking Traffic Systems," Andrew Lemon, CEO of Red Threat, delivers a high-octane exploration into the vulnerabilities of intelligent transportation systems (ITS). This talk serves as a condensed, yet comprehensive, introduction to the complex world of traffic light controllers, their underlying protocols, and the surprisingly accessible attack vectors that exist within these critical infrastructure components. Lemon, drawing from 13 years of professional pentesting experience, demystifies how these systems operate, how they can be acquired for legitimate research, and the significant security flaws that, if exploited, could lead to widespread disruption and safety hazards.
