From car jacking to car hacking. That's the concern that Spanish security researchers plan to introduce at next month's Black Hat Asia Security Conference, where Forbes reports that they'll be introducing a $20 device that can inject malicious commands into a card through its internal network of electronics. This CAN Hacking Tool taps into a vehicles Controller Area Network protocol, a protocol standard introduced in 1986 that can be accessed though a vehicle's OBD-II port--yes, the same jack that you would plug the Automatic iOS gadget. This is far from the first time that researchers have demonstrated how relatively easy it is to tap into a vehicle's basic functions through unsecured connections, and Forbes' own Andy Greenberg took a test drive in a car-hacked Ford Escape last year. You can watch that video below.
