The laser apparatus used by most self-driving cars can be hacked with a glorified laser pointer that costs just $60, Spectrum reports.
Most prototype self-driving cars use a kind of laser technology similar to radar to detect and evade objects in front of them, like pedestrians or other vehicles.
Jonathan Petit, a research fellow at the University College of Cork, Ireland, has discovered how to use a low-power laser and a pulse generator to trick an autonomous car into thinking it is surrounded by obstacles, thereby either forcing it to slow down or immobilizing it altogether.
“I can take echoes of a fake car and put them at any location I want. And I can do the same with a pedestrian or a wall,” Petit told Spectrum. “I can spoof thousands of objects and basically carry out a denial of service attack on the tracking system so it’s not able to track real objects.”
Petit will present his “off the shelf” hack at the Black Hat Europe security conference in November.
The paper comes amongst proliferating reports of hackable cars. On Friday, Fiat Chrysler announced that it is recalling 7,810 vehicles that are equipped with a radio vulnerable to hacking. The recall follows another Fiat Chrysler recall of roughly 1.4 million vehicles earlier this summer.
