I've shown you scary car hacks before, but this one might take the cake.
Australian security researcher Silvio Cesare discovered a way to use a wireless car key fob to unlock any car without a trace. He plans to reveal his technique at the upcoming Black Hat Security Conference later this week.
Making the fob will cost a little bit over $1,000 in supplies and uses a radio that can connect to the car via FM radio signals, Bluetooth and Wi-Fi to transmit the same frequency that is used to unlock the car.
The signals used takes guesses at thousands of codes at a rate of two or three per second, so the hack isn't instant. In some cases it can take up to two hours to crack the code.
However, in the video demonstration of the hack - which you can see below from Wired - only took a few minutes.
With wireless entry, there's no sign of a break in. Anyone who leaves their car parked overnight or for more than a period of two hours could be at risk. The only sign that anyone has broken in is that the original key fob won't work the next time the car owner tried to use it.
The good news here is that Cesare isn't going to unleash his information to bad hackers.
Ultimately, Cesare says it may be too late to protect the vulnerable generation of cars he’s discovered, and he intends his findings to instead serve as a warning to automakers for future models. For that reason he’s declined to make his code or tools available to the public for fear of enabling less technically-skilled thieves. “Criminals could hire researchers to replicate this attack,” he says. “But they won’t be getting it from me.”
