Hackers Could Steal a Tesla Model S by Cloning Its Key Fob—Again
Just like they did about a year ago, security researchers at a Belgian university have demonstrated that they could steal Tesla Model S vehicles by cloning the key fob. In order to fix the previously discovered flaw, which allowed for remote attacks, Tesla replaced all old key fobs with an improved version last year. However, the researchers have now discovered a vulnerability in the new key fob that can be exploited from within the vicinity of a car.
The flaw is a configuration issue that makes it possible to break the key fob’s encryption, although this process now requires twice the computing power as was true for the old key fob. The new vulnerability has been fixed by Tesla via a software update, because a hardware solution was not necessary this time.
