DESCRIPTION: To test out GPS security, researchers demonstrate how to steal a cargo truck and get away with it. Cargo trucks generally contain a GPS tracking device which relays position and speed information to a central office. This enables freight companies to track their drivers’ locations and ensure that trucks are on course. If a truck veers off course, it sets off an alarm at headquarters. If an attacker could falsify or “spoof” GPS information, he or she could hijack the truck and steal the cargo without being noticed.
