“A security researcher has discovered a way to locate, hack and unlock Tesla Motors premiere Model S from a remote computer using traditional hacking techniques. Nitesh Dhanjani announced his findings at the Black Hat Asia security conference in Singapore over the weekend, where the author of multiple books on hacking revealed that by cracking a six-character password transmitted wirelessly over the Internet, a hacker could locate and gain access to any Model S. Using Dhanjani’s technique, hackers could find and break into Teslas to steal any contents inside the car, but would be unable to hijack and drive the car itself, which requires the owner’s electronic key fob.”
