Security researchers believe they have found a hardware exploit to unlock upgrades to a Tesla that normally require plenty of extra cash. By messing with the voltage of the infotainment system, they were able to inject their code, bypassing its normal security. That enabled them to access personal data, including GPS tracking and call logs, as well as the car's encryption key. That, the researchers claim, could be the key to unlocking paywalled features, like the mode known as Full Self-Driving, which you presently have to pay extra to use. That's not the only slice of bad news on Tesla's breakfast plate today; it also stands accused of fraud.
