Tesla Autopilot Tricked Into Accelerating from 35 to 85 MPH by Speed Limit Sign Modified with Two Inches of Tape
February 21st, 2020Via: MIT Technology Review:
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.
