“For this, we are using a known voltage fault injection attack against the AMD Secure Processor (ASP), serving as the root of trust for the system.”
Tesla ships every car with the same hardware and charges to switch on heated rear seats and faster acceleration. TU Berlin researchers glitched the AMD chip, got root, and say the jailbreak is unpatchable. They also pulled the car’s unique RSA key for Tesla’s service network. When the seat heater needs a root of trust, the owner is the threat model.
