Hackers conquer Tesla’s in-car web browser and win a Model 3

NelsonG · March 24, 2019

A pair of security researchers dominated Pwn2Own, the annual high-profile hacking contest, taking home $375,000 in prizes including a Tesla Model 3 — their reward for successfully exposing a vulnerability in the electric vehicle’s infotainment system.

Tesla handed over its new Model 3 sedan to Pwn2Own this year, the first time a car has been included in the competition. Pwn2Own is in its 12th year and run by Trend Micro’s Zero Day Initiative. ZDI has awarded more than $4 million over the lifetime of the program.

The pair of hackers Richard Zhu and Amat Cam, known as team Fluoroacetate, “thrilled the assembled crowd” as they entered the vehicle, according to ZDI, which noted that after a few minutes of setup, they successfully demonstrated their research on the Model 3 internet browser.

The pair used a JIT bug in the renderer to display their message — and won the prize, which included the car itself. In the most simple terms, a JIT, or just-in-time bug, bypasses memory randomization data that normally would keep secrets protected.

Tesla told TechCrunch it will release a software update to fix the vulnerability discovered by the hackers.

“We entered Model 3 into the world-renowned Pwn2Own competition in order to engage with the most talented members of the security research community, with the goal of soliciting this exact type of feedback. During the competition, researchers demonstrated a vulnerability against the in-car web browser,” Tesla said in an emailed statement. “There are several layers of security within our cars which worked as designed and successfully contained the demonstration to just the browser, while protecting all other vehicle functionality. In the coming days, we will release a software update that addresses this research. We understand that this demonstration took an extraordinary amount of effort and skill, and we thank these researchers for their work to help us continue to ensure our cars are the most secure on the road today.”

That's a wrap! Congrats to @fluoroacetate on winning Master of Pwn. There total was $375,000 (plus a vehicle) for the week. Superb work from this great duo. pic.twitter.com/Q7Fd7vuEoJ

Pwn2Own’s spring vulnerability research competition, Pwn2Own Vancouver, was held March 20 to 22 and featured five categories, including web browsers, virtualization software, enterprise applications, server-side software and the new automotive category.

Pwn2Own awarded a total of $545,000 for 19 unique bugs in Apple Safari, Microsoft Edge and Windows, VMware Workstation, Mozilla Firefox, and Tesla.

Tesla has had a public relationship with the hacker community since 2014 when the company launched its first bug bounty program. And it’s grown and evolved ever since.

Last year, the company increased the maximum reward payment from $10,000 to $15,000 and added its energy products as well. Today, Tesla’s vehicles and all directly hosted servers, services and applications are now in scope in its bounty program
