Tesla vehicles are helpless against thieves using Bluetooth!

A research team has developed a tool that successfully bypasses all existing security measures with the Bluetooth Low Energy (BLE) attack and can authenticate at target points. This type of attack can be effective on all types of devices, from smartphones to smart locks. The researchers chose a Tesla-branded car for the experiment.

Tesla vehicles and many devices are in danger!
The attack is carried out over signals between the official Bluetooth sender and receiving devices. In this way, the attacker can manipulate the data sent to the receiving device. All that is required to implement this method is for the attacker to be relatively close to both the user and the target device.

In the experiment, the researchers used a 2020 Tesla Model 3 with version 4.6.1-891 of the Tesla app and an iPhone 13 mini. During the experiment, two relay devices were used, one seven meters from the phone and the other three meters from the car. The total distance between the phone and the car was 25 meters. And the experiment ended successfully.

The researchers made the following statements on the subject:

“NCC Group was able to use this newly developed relay attack device to unlock and start the vehicle when the iPhone was out of BLE range.

Later, the team successfully performed the same experiment on the 2021 Tesla Model Y. The research team shared the results of the experiment with Tesla. Tesla said the relay attacks were “a known flaw of the passive entry system.”

To protect against such attacks, users can disable the passive entry system. They may also use an alternative authentication method in their tools, preferably requiring user interaction. In addition to these, the “PIN to Drive” feature is also a very important point for the security of your vehicle. Thanks to this, even if the thieves manage to successfully open the vehicle, they will not be able to get too far away.
