He's also only tested it on his own car, which is ten years old.īut the radio equipment Cesare used in his research and proof-of-concept attack is rapidly getting cheaper, potentially inviting less friendly hackers to refine his technique and seek out similar wireless vulnerabilities. “It effectively defeats the security of the keyless entry.” For now, Cesare's hack requires off-the-shelf tools that cost just over $1,000, and in some cases may require the attacker to remain within wireless range of the car for as long as two hours. “I can use this to lock, unlock, open the trunk,” says Cesare, an Australian researcher for the security firm Qualys. As part of a at the Black Hat security conference later this week, Cesare plans to reveal a technique that could allow anyone to spoof the signal from a wireless key fob and unlock a car with no physical trace, using a codebreaking attack that takes as little as a few minutes to perform. Modern-day thieves, if they're as clever as Silvio Cesare, may be able to unlock your vehicle’s door without even touching it. Shims and coat hangers are the clumsy tools of last century's car burglars.
