Hackers used “voltage glitching” to unlock Tesla’s premium features like $300 heated seats and to hijack personal information.
According to a report in TechCrunch, three students from Technische Universität Berlin and an independent researcher used a method called voltage glitching for a digital-age hot wire by messing with the power supply of the infotainment system’s AMD processor.
The hack will be presented at next week’s Black Hat conference in Las Vegas.
“If we do it at the right moment, we can trick the CPU into doing something else,” said Christian Werling, one of the students, in an interview with TechCrunch.
“It has a hiccup, skips an instruction, and accepts our manipulated code. That’s basically what we do in a nutshell.”
The attack doesn’t just unlock the $300 heated seat features.
(Also, can you believe you need to pay $300 for something that’s already built into your car?)
The researchers said they were able to unlock the encryption key that authenticates the car on Tesla’s network, which could pave the way for unlocking even more features, such as enabling things like Full Self-Driving even in regions where the technology is prohibited.
