Laser Pointer Hack Easily Dupes Driverless Cars

A simple off-the-shelf laser pointer could be combined with a very basic computer to disrupt the multithousand-dollar laser ranging, or Lidar, systems installed in most self-driving cars, a security researcher warned last week. A setup that costs about $60 could trick the Lidar system, which autonomous vehicles use to sense objects in the road, into responding as though there were obstacles ahead in situations where there were none, said Jonathan Petit, principal scientist at Security Innovation.
