Hacker finds way to unlock Tesla models, start cars

Tesla Inc. customers might love the carmakers’ nifty keyless entry system, but one cybersecurity researcher has demonstrated how the same technology could allow thieves to drive off with certain models of the electric vehicles.

A hack effective on the Tesla Model 3 and Y cars would allow a thief to unlock a vehicle, start it and speed away, according to Sultan Qasim Khan, principal security consultant at the Manchester, UKbased security firm NCC Group. By redirecting communications between a car owner’s mobile phone, or key fob, and the car, outsiders can fool the entry system into thinking the owner is located physically near the vehicle.

The hack, Khan said, isn’t specific to Tesla, though he demonstrated the technique to Bloomberg News on one of its car models. Rather, it’s the result of his tinkering with Tesla’s keyless entry system, which relies on what’s known as a Bluetooth Low Energy protocol.

There’s no evidence that thieves have used the hack to improperly access Tesla vehicles. The carmaker didn’t respond to a request for comment.
