Researchers were able to fool popular autopilot systems into perceiving projected images as real causing the cars to brake or veer into oncoming traffic lanes. Attackers could potentially leverage this design hole to trigger the systems to brake, steer cars into traffic lanes, they said. The issue stems from advanced driving assistance systems (ADAS) which are used by semi-autonomous vehicles to help the vehicle driver while driving or parking. Researchers said that phantom attacks have not yet been encountered in the wild.
