CSM Exclusive: Iran hijacked US drone, says Iranian engineer

[T]his engineer’s account of how Iran took over one of America’s most sophisticated drones suggests Tehran has found a way to hit back. The techniques were developed from reverse-engineering several less sophisticated American drones captured or shot down in recent years, the engineer says, and by taking advantage of weak, easily manipulated GPS signals, which calculate location and speed from multiple satellites.

I’m pretty sure “weak, easily manipulated GPS signals” is a sphincter-clench-inducing phrase in some circles.
