Researchers jailbreak a Tesla to get free in-car feature upgrades

Researchers have found a way to hack the hardware of Tesla's infotainment system, allowing them to access paid upgrades for free and potentially enable self-driving and navigation systems in restricted regions.

Key points:

1. Researchers have discovered a method to jailbreak Tesla cars and access paid upgrades without payment.
2. The hack requires physical access to the car, making it useful for owners who want to avoid paying for upgrades.
3. The technique used is called voltage glitching, which manipulates the supply voltage of the infotainment system's processor.
4. The researchers were also able to extract the encryption key used to authenticate the car to Tesla's network.
5. Personal information, such as contacts, calendar appointments, and Wi-Fi passwords, can also be accessed.
6. Mitigating the attack would require Tesla to replace the affected hardware.
