Researchers at the University of Leuven in Belgium found vulnerabilities in the keyless entry system of the Tesla Model X that would have allowed attackers to steal the $100,000 car within just a few minutes. The security bugs allowed taking full control of the key fob and of the car by remotely updating the Model X’s BLE chip with specially crafted firmware. Tesla is rolling over-the-air firmware update to address the issues affecting the keyfob. The company’s Model 3 car Chromium-based infotainment system was hacked during last year’s Pwn2Own competition by Fluoroacetate’s Amat Cama.
