OwnStar – Vulnerability in OnStar Application for GM vehicles

Hack of OnStar Remotelink lets attacker unlock, remote-start, and track cars.

The OwnStar device can detect nearby users of the OnStar RemoteLink application on a mobile phone and can then inject packets into the communication stream to the phone, getting it to give up additional information about the user’s credentials. Those credentials can then be used to gain access to the vehicle’s OnStar account and the full functionality of the OnStar RemoteLink app.

Kamkar says the vulnerability is in the app itself and not the OnStar hardware in GM vehicles. He added that GM and OnStar are working to correct the flaw in the vulnerable mobile application. GM customers who use OnStar can protect themselves for the time being by not using the RemoteLink app.

Good thing I don’t have a GM vehicle that heavily uses OnStar remote services.
