#gps-spoofing

As The Register has previously reported, attackers who wish to jam GPS broadcast a radio signal that can drown out the weak beams that come down from navigation satellites. Spoofing a signal sees attackers transmit inaccurate location information so receivers can't calculate their actual position. Either technique means pilots can't rely on satellite navigation - doing so could be catastrophic - and must instead find their way using other means.

Over years of flying, it had been drilled into the crew to pull back on the controls when such an alarm sounded, but on this occasion the pilot took no action. The crew were prepared for their system to make spurious warnings and knew from experience they were still flying at a safe altitude.
