Hackers have manipulated multiple Tesla cars into speeding up by 50 miles per hour. The researchers fooled the car’s Mobileye EyeQ3 camera system by subtly altering a speed limit sign on the side of a road in a way that a person driving by would almost never notice.
This demonstration from the cybersecurity firm McAfee is the latest indication that adversarial machine learning can potentially wreck autonomous driving systems, presenting a security challenge to those hoping to commercialize the technology.
Mobileye EyeQ3 camera systems read speed limit signs and feed that information into autonomous driving features like Tesla’s automatic cruise control, said Steve Povolny and Shivangee Trivedi from McAfee’s Advanced Threat Research team.
The researchers stuck a tiny and nearly imperceptible sticker on a speed limit sign. The camera read the sign as 85 instead of 35, and in testing, both the 2016 Tesla Model X and that year’s Model S sped up 50 miles per hour.
The modified speed limit sign reads as 85 on the Tesla’s heads-up display. A Mobileye spokesperson downplayed the research by suggesting this sign would fool a human into reading 85 as well.
