Security researchers have demonstrated a new Bluetooth relay attack that can remotely unlock and operate some Tesla vehicles.
The vulnerability lies in Bluetooth Low Energy (BLE), the technology used by Tesla’s entry system that allows drivers with the app or key fob to unlock and operate their car from nearby. Most devices and vehicles that rely on this kind of proximity-based authentication are designed to protect against a range of relay attacks, which typically work by capturing the radio signal used for unlocking a vehicle, for example, and replaying it again as if it were an authentic re
