Tesla has rushed to release a patch within 10 days of Chinese white hat hackers’ (security researchers) discovery of vulnerabilities within the Model S’ control system that allowed for an intruder to remotely breach the system.
Chinese security researchers have successfully demonstrated their hacking prowess by remotely connecting to a Tesla Model S when the vehicle was both dormant and in motion.
The researchers from Keen Security Lab, a unit of China’s Tencent Holdings Ltd., published a video with an accompanying blog that revealed the hack. In it, the researchers remotely infiltrated the Model S’ controller area network bus, the unit responsible for intra-auto computer communication. Once they gained access, the researchers were able to manipulate and later safety controls, the breaking systems and the door locks.
The hackers were able to target and successfully compromise the popular electric car from up to 12 miles away, while the cars were still in motion.
As all white-hat researchers do responsibly, the hacking trio of researchers withheld details of the vulnerability and their zero-day exploit to privately disclose the flaws to Tesla.
In their blog, the researchers wrote:
As far as we know, this is the first case of remote attack which compromises CAN Bus to achieve remote controls on Tesla cars. We have verified the attack vector on multiple varieties of Tesla Model S. It is reasonable to assume that other Tesla models are affected.
For its part, Tesla released a statement to reveal that a patch was developed and deployed within 10 days of receiving the vulnerability report from the security researchers. The carmakers insisted that the exploit was only triggered when its web browser was used, while underlining that the car required to be physically within the range of and connected to a malicious Wi-Fi hotspot.
Altogether, Tesla assessed the realistic risk posed to its customers was “very low,” while adding that it the threat estimate did not stopping the company and its security team from “responding quickly.”
Tesla is at an advantage when compared to most other carmakers, when releasing a patch. The company can directly push security patches and updates OTA (over-the-air) to its cars’ computer systems, wherever they are.
