Researchers have found another way to clone potential Model S keychains



Apparently, the vulnerability allowed hackers to break 80-bit encryption by cracking two 40-bit keys instead. The new attack has a shorter range than the first and takes a little longer than a few seconds, but is still feasible. However, model S owners do not have to worry about bad actors taking the mistake of breaking into their cars ̵

1; all they have to do is upgrade their supporters. Tesla has already fixed the problem and, in contrast to last year, does not need any new hardware. The automaker has begun to introduce a wireless software update for existing key fobs. In fact, the change was implemented last month for all newly manufactured Model S vehicles, so new owners do not even need to upgrade.

Wouters was impressed with the way Tesla dealt with the problem, but warned him that many key fobs on other cars are susceptible to similar encryption-cracking techniques. Especially as most automakers purchase their third party key fobs and some of them are unable to transmit updates via radio, as is the case with Tesla.

As for Tesla, the automaker seems confident that its vehicles are working safely enough. A spokesman said in a statement to Wired that last year the company introduced a PIN-to-drive feature that allowed owners to prevent someone from driving their vehicle when they can not enter the correct PIN. [19659002] The spokesperson said:

"Although nothing can protect against all vehicle theft, Tesla has implemented several security enhancements, such as the the-air software update (part of 2019.32), which takes up and determines the findings of this researcher Model S owners can upgrade their key fobs in the car in less than two minutes, releasing to existing owners as we are able to provide wireless updates that enhance the functionality and safety of our cars and key fobs.
