I recently wrote about a vehicle hacking demonstration which exposed serious vulnerabilities in a 2014 Chrysler Jeep Cherokee in “Hack my ride.” As expected, the threat extended well beyond that specific make and model and resulted in the recall of 1.4 million vehicles that were affected by the vulnerability.
Don’t feel smug because you don’t drive one of those models because the hits keep coming…
Here’s one that affects GM’s OnStar system, specifically, the mobile app that allows for remote access of vehicle functions. As you can see in this video below, it is possible to create a good deal of havoc with little more than about $100’s worth of equipment.
When the driver comes within Wi-Fi range of Kamkar’s $100 contraption, which he’s named “OwnStar” in a reference for the hacker jargon to “own” or control a system, it impersonates a familiar Wi-Fi network to trick the user’s phone into silently connecting.
a hacker could patiently track a car, retrieve his or her hacking device, and unlock the car’s doors to steal anything inside. From across the Internet, they can start the vehicle’s ignition, or use its horn and alarm to create mayhem. The hacker can also access the user’s name, email, home address, and last four digits of a credit card and expiration date, all of which are accessible through an OnStar account.
The good news? This one should be fixable with a patch to the mobile app.
The bad news? Expect to see more of these sorts of car hacks to come.
