DEF CON 32 Creator Stage · Day 1 · Creator Stage
This talk, presented by Seunghee Han of Autocrypt at DEF CON 32, unveiled critical safety vulnerabilities discovered in "latest EV models" through the application of **UDS (Unified Diagnostic Services)** fuzzing techniques. The presentation highlights a significant security oversight where fundamental diagnostic services, intended for repair and testing, remain active and exploitable while a vehicle is in motion, directly contravening established automotive cybersecurity standards.
