Hacking Learning Codes in Car Key Fobs - Hardware Security Analysis

Explore a 27-minute conference talk from DEF CON that demonstrates how to exploit vulnerabilities in car key fobs using hardware hacking techniques. Learn about the process of disassembling a key fob to identify the HS2240 integrated circuit and using a logic analyzer to examine learning code transmissions between the circuit and RF LED emitter. Discover how HackRF Software Defined Radio can be utilized to duplicate learning codes, enabling unlimited vehicle access without the original key. Understand why learning codes present similar security vulnerabilities as fixed codes in automotive security systems, with practical demonstrations from a widely-used vehicle model.
