Researchers from University of California at San Diego say they can hack into thousands of cars through a device used by insurance companies to monitor vehicles' location and speed. "By sending carefully crafted SMS messages to one of those cheap dongles connected to the dashboard of a Corvette, the researchers were able to transmit commands to the car’s CAN bus -- the internal network that controls its physical driving components—turning on the Corvette’s windshield wipers and even enabling or disabling its brakes," Wired writes.
