Objects in Driverless Car Sensors may be Closer Than They Appear

Researchers have shown that a popular method to secure LiDAR sensors against "naive attacks" is still vulnerable at longer distances and only works at short distances. Here, a LiDAR system is fooled into thinking a car is somewhere else until it becomes too late to avoid a sudden and drastic course correction.

Researchers at Duke University have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensors into believing nearby objects are closer (or further) than they appear without being detected. The research suggests that adding optical 3D capabilities or the ability to share
