With several months of in-depth research on Tesla Cars, we have discovered multiple security vulnerabilities and successfully implemented remote, aka none physical contact, control on Tesla Model S in both Parking and Driving Mode. It is worth to note that we used an unmodified car with latest firmware to demonstrate the attack.
Following the global industry practice on “responsible disclosure” of product security vulnerabilities, we have reported the technical details of all the vulnerabilities discovered in the research to Tesla. The vulnerabilities have been confirmed by Tesla Product Security Team.
Keen Security Lab appreciates the proactive attitude and efforts of Tesla Security Team, leading by Chris Evans, on responding our vulnerability report and taking actions to fix the issues efficiently. Keen Security Lab is coordinating with Tesla on issue fixing to ensure the driving safety of Tesla users.
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. Keen Security Lab would like to send out this reminder to all Tesla car owners:
PLEASE DO UPDATE THE FIRMWARE OF YOUR TESLA CAR TO THE LATEST VERSION TO ENSURE THAT THE ISSUES ARE FIXED AND AVOID POTENTIAL DRIVING SAFETY RISKS.
The video below demonstrates the impact of our remote attack vector. REMINDER: WHAT YOU ARE ABOUT TO SEE IN THIS VIDEO ARE PERFORMED BY PROFESSIONAL RESEARCHERS, DO NOT TRY THIS AT HOME.
