Argentinian researchers have built a device to spy on internal communications and deliver commands to the vehicle. The piece of hardware has GSM support, allowing an attacker to activate available payloads by sending an SMS from anywhere in the world. The device is a hardware backdoor that connects through the OBD-II port to a vehicles CAN bus. The two researchers say the attack payloads can be configured for automatic execution according to specific circumstances. They will present their work at the Hack in the Box security conference in Amsterdam, on April 13.”]
