An anonymous reader quotes a report from Reuters: Tesla Motors Inc has rolled out a security patch for its electric cars after Chinese security researchers uncovered vulnerabilities they said allowed them to remotely attack a Tesla Model S sedan. The automaker said that it had patched the bugs in a statement to Reuters on Tuesday, a day after cybersecurity researchers with China'a Tencent Holdings Ltd disclosed their findings on their blog. Tesla said it was able to remedy the bugs uncovered by Tencent using an over-the-air fix to its vehicles, which saved customers the trouble of visiting dealers to obtain the update. Tencent's Keen Security Lab said on its blog that its researchers were able to remotely control some systems on the Tesla S in both driving and parking modes by exploiting the security bugs that were fixed by the automaker. The blog said that Tencent believed its researchers were the first to gain remote control of a Tesla vehicle by hacking into an onboard computer system known as a CAN bus. In a demonstration video, Tencent researchers remotely engaged the brake on a moving Tesla Model S, turned on its windshield wipers and opened the trunk. Tesla said it pushed out an over-the-air update to automatically update software on its vehicles within 10 days of learning about the bugs. It said the attack could only be triggered when a Tesla web browser was in use and the vehicle was close enough to a malicious Wi-Fi hotspot to connect to it.
