Tesla Hacked Twice at Pwn2Own Exploit Contest

Researchers at French offensive hacking shop Synacktiv have demonstrated a pair of successful exploit chains against Tesla’s newest electric car to take top billing at the annual Pwn2Own software exploitation contest.

Pwn2Own organizers confirmed the successful hacks exploited flaws in the Tesla-Gateway and Tesla-Infotainment sub-systems to “fully compromise” a new Tesla Model 3 vehicle.

The first Tesla hack, described as a TOCTOU (time-of-check to time-of-use) race condition, earned the hackers a $100,000 cash prize and ownership of the compromised car.  Synacktiv said the Tesla Model 3 gateway was fully compromised from the ethernet network.

SecurityWeek sources say Tesla security response team was on site at the event and validated the findings.  The company is expected to issue fixes via the vehicle’s self-updating system.

On the second day of the contest in Vancouver, Canada, Synacktiv’s researchers created an exploit chain that used a heap overflow and an out-of-band (OOB) write vulnerability to pop the Tesla-Infotainment system.  The hack was described as “Unconfined Root” and scored the Synacktiv team a $250,000 cash prize.
