All Your GPS Are Belong To Us: Towards Stealthy Manipulation of Road Navigation Systems
summary
Researchers build a low-cost portable GPS spoofer (~$323) and an algorithm that computes subtle GPS shifts so fake turn-by-turn routes match real road geometry. Simulations on 600 taxi traces (Manhattan/Boston) and real driving tests show takeovers in ~40 s, an effective range of 40–50 m, diversions of 2.1–2.5 km, many routes that enable wrong-way or hazardous deviations, and a 95% follow rate in driving-simulator user studies.
