UDSonCAN Attacks - Discovering Safety Critical Risks by Fuzzing

Learn about critical automotive security vulnerabilities discovered through UDSonCAN fuzzing in this 23-minute conference talk from DEF CON 32. Explore how diagnostic messages can be exploited to create serious safety risks in vehicles when proper authentication mechanisms are absent. Examine real-world examples where simple diagnostic commands could force sudden stops in moving vehicles or unexpected acceleration in stationary ones. Discover the findings from vulnerability research conducted on a modern electric vehicle model, complete with demonstration footage. Understand the essential countermeasures needed to protect against these UDSonCAN attacks and strengthen vehicle security systems.
