Your Car Key Fob's Security: A Closer Look at Vulnerabilities
This technical article delves into the security vulnerabilities of Remote Keyless Systems (RKS) used in car key fobs. Using a 2006 Prius as an example, it explains how Software Defined Radio (SDR) can be used to receive and analyze key fob signals, revealing the rolling code mechanism. While rolling codes enhance security, the article details various attack methods like replay attacks, jamming, and signal amplification, enabling car theft. Higher-end Passive Keyless Entry and Start (PKES) systems are also examined, along with a case study on a vulnerability in VW's RKS system exploiting a repeated key flaw across millions of cars. The article concludes with assignment suggestions for further exploration of car security vulnerabilities and countermeasures.
