Tesla hackers explain how they did it
It is very difficult and to hack a Tesla Model S, but it's not impossible. Last week, researchers Kevin Mahaffey and Marc Rogers demonstrated that they were able to remotely unlock the Model S' doors, start the vehicle and drive away. They were also able to issue a "kill" command to a Model S to shut down the vehicle's systems, bringing it to a stop. Then, at this weekend's the DEF CON 23 digital security conference, they showed all in attendance how they did it.
