Researchers from Virginia Polytechnic Institute and State University, the University of Electronic Science and Technology of China, and Microsoft Research have demonstrated an effective global-positioning system (GPS) spoofing hack against road navigation systems that takes the road layout into account.
The team engineered an algorithm that operates in near-real time, in conjunction with a portable GPS-spoofing device affixed to a car or put on a vehicle following the target's car at distances of up to 50 meters.
"The algorithm crafts the GPS inputs to the target device such that the triggered navigation instruction and displayed routes on the map remain consistent with the physical road network," the researchers say. "In the physical world, the victim who follows the instruction would be led to a wrong route (or a wrong destination)."
The team found 95% of participants were tricked in this way.
