We'll go over how a train control system actually works, how we reverse-engineered one and what sort of magical “security” systems we actually found inside of it.\n\nReality sometimes is stranger than the wildest CTF task. Reality sometimes is running `unlock.py` on a dozen trains.\n\nThe talk will be a mix of technical and non-technical aspects of analysis which should be understandable for anyone with a technical background. We’ll briefly explain how modern EMUs look like inside, how the Train Control & Monitoring System works, and how to analyze TriCore machine code.",
