Don Bailey unlocks and starts cars with BMW Assist, GM OnStar and Ford Sync by SMS message.
Don Bailey and Mathew Solnik have found a way to unlock cars that use remote control and telemetry systems like BMW Assist, GM OnStar, Ford Sync, and Hyundai Blue Link.
These systems communicate with the automaker’s remote servers via standard standard mobile networks like GSM and CDMA. The hackers faked the server to communicate directly with a car’s on-board computer.
They showed their techniques at the Black Hat USA conference in Las Vegas in a briefing entitled War Texting: Identifying and Interacting with Devices on the Telephone Network.
Software that lets drivers unlock car doors and start their vehicles using a mobile phone could let car thieves do the very same thing.
