A security researcher has posted a video on YouTube demonstrating how a device he made can intercept wireless communications to locate, unlock and remotely start GM vehicles that use the OnStar RemoteLink mobile app.
Samy Kamkar, who refers to himself as a hacker and whistleblower, posted the video today showing him using a device he calls OwnStar. The device, he said, intercepts communications between GM’s OnStar RemoteLink mobile app and the OnStar cloud service.
