This story originally appeared on Ars Technica. So for me, there was no point in talking to Tesla beforehand." "This time, there is no way that Tesla does not know about that poor implementation. "My impression was that they always already knew and would not really change stuff," he said. Another protection is to regularly check the list of keys authorized to unlock and start the car through a process Tesla calls "whitelisting." Tesla owners may want to perform this check after giving an NFC card to an untrusted mechanic or valet parking attendant.īased on the lack of response Herfurt said he received from Tesla regarding vulnerabilities he uncovered in 2019 and again last year, he's not holding his breath that the company will address the issue. One countermeasure is to set up Pin2Drive to prevent thieves who use this method from starting a vehicle, but it will do nothing to prevent the thief from being able to enter the car when it's locked. With Tesla maintaining radio silence on this weakness, there's only so much that concerned owners can do. Comsoon Bluetooth : Runner-Up Aux Connection Bluetooth Adapter. Anker Roav Bluetooth Car Adapter : Best FM Bluetooth Adapter. This method isn't likely to be practical in many theft scenarios, but for some, it seems viable. Nulaxy KM30 : Runner-Up FM Bluetooth Adapter. The attack is easy enough in technical aspects to carry out, but the mechanics of staking out an unattended vehicle, waiting for or forcing the owner to unlock it with an NFC card, and later catching up with the car and stealing it can be cumbersome. Some fob devices operate such that when a key is pressed on the fob, the device sends a code to the vehicle to instruct the vehicle to unlock the vehicle. Vehicle key fobs may be used to allow a user to gain access to a vehicle. Herfurt created Teslakee as part of Project Tempa, which “provides tools and information about the VCSEC protocol used by Tesla accessories and the Tesla app in order to control vehicles via Bluetooth LE.” Herfurt is a member of Trifinite Group, a research and hacker collective that focuses on BLE. The Cube Pro delivers maximum performance for those in the market for a Bluetooth key finder Credit: Ross Patton 2 Multiple Tags With Easy Setup and Use Esky Key Finder 20 at Amazon Dimensions: 32 x 32 6.8 mm Weight: 10. multiple vehicles and multiple frequencies to connect to the vehicles via a Bluetooth Low Energy Module (BLEM). Teslakee will communicate with any vehicle if it is told to. This would not work with the official app, but an app that is also able to speak the Tesla-specific BLE protocol … allows attackers to enroll keys for arbitrary vehicles. Any attacker who can see the Bluetooth LE advertisements of a vehicle may send VCSEC messages to it. There is no connection between the online account world and the offline BLE world. This works because Tesla's authorization method is broken. The attack exploits Tesla's way of handling the unlock process via NFC card. It not only opens a locked car and starts it it's also used to authorize key management. The vulnerability is the result of the dual roles played by the NFC card. Theyre quite easy to use: a key finder or Bluetooth GPS key tracker has a built-in Bluetooth chip with a maximum signal range of 50 metres between the.
