Outside Remote hacks, self driving cars are also vulnerable to hacks that is a short distance 'them. It does not need expensive tools to do so. It can be done using cheap electronics too.
Jonathan Little, a security researcher, proved that you can fool LIDAR (laser ranging commong on autonomous vehicles) by sending laser pulses so that the car driving might think there another car or other object nearby, whereas in reality, the objects do not exist. All is needed is a low-power laser, basic computing device such as Arduino or Raspbery Pi kit and good timing.
In his attack on proof of concept, Petit presented that is capable of creating an imaginary objects as far as 330 feet away and he was also able to create multiple copies of it and the move along. The impact of it in the auto car driving is that these imaginary objects is able to stop or move because it is designed to avoid threats.
The method of Small works only if the unit LIDAR pulses are not encrypted, so it is possible to avoid this kind of piracy if the auto ready car driving output is encrypted when sending LIDAR unit pulses. However, it is unclear if this will be a big problem and it becomes pretty common question for self driving.
