Flaws in BMW onboard computer systems could allow attackers to remotely take partial control of vehicles, the BBC reports.
An investigation by Keen Lab, a division of Tencent, found 14 separate vulnerabilities in different in-car systems which could theoretically allow a hacker to gain some control over the car from hundreds of metres away, even while the car is driving.
Security researchers found that systems could be compromised through contactless means such as Bluetooth and 3G and 4G data links, or through USB drives.
Researchers identified three main systems which were vulnerable to attack, including the in-car infotainment systems, including sat-nav guidance, radio-station playback, car diagnostic information, and voice-recognition services; the telematics control unit which provides location tracking, and the central gateway which links various electronic control units (ECUs) and other connected systems in the car.
BMW said it is working on fixes for the problems, and that users should be aware that updates will be made available soon.
