Tesla has known about the hack since August, researchers say, but still hasn't issued an update.
90 Second Hack
Security researchers from Belgium have figured out a way to hack into a Tesla Model X by overwriting the firmware of the car's key fob via a Bluetooth connection, Wired reports.
The hack, which KU Leuven security researcher Lennert Wouters told Wired Tesla still hasn't addressed, could let a thief steal an entire Model X within 90 seconds.

Wouters combined two vulnerabilities, according to Wired. The first lets a hacker get inside a Model X with a hacked key fob using the car's vehicle identification number, which is normally printed on the dashboard where it can be read from outside the car.
The second used a custom piece of hardware that Wouters told Wired he built for about $300 using a modified Model X body control module, which he says the hacker could plug into a port on the Tesla's dashboard after gaining access to the inside of the vehicle. The second hack, he said, gives the thief full control of the car.
"Basically a combination of two vulnerabilities allows a hacker to steal a Model X in a few minutes time," Wouters told Wired. "When you combine them, you get a much more powerful attack."
Key Fob Rob
It's yet another instance of a security vulnerability involving Tesla key fobs allowing hackers to get inside locked up vehicles. Last year, home security videos surfaced showing thieves hacking into a Tesla using a device with a long antenna.
Wouters told Wired that he warned Tesla about the latest hack back in August. But it doesn't plan to roll out a software update to fix either vulnerability until this coming week.
Tesla didn't reply to Wired's request for comment — which could be related to the fact that it dissolved its PR department earlier this year.
