FBI says car hacking is a real risk

Connected cars are becoming "increasingly vulnerable" to cyberattack, according to an advisory issued Thursday by the FBI and the US National Highway Traffic Safety Administration.

In its public service announcement, the FBI outlined the kinds of hacks security researchers have been able to perform. In a target vehicle traveling at low speeds (5-10 mph), researchers were able to shutdown an engine as well as disable brakes and steering. In a target vehicle traveling at any speed, they were able to control door locks, radio, GPS and the turn signals.
