I remember a story a while back (Maybe 5 years?) about an enemy that stole an unmanned drone by broadcasting spoof GPS so it thought it was somewhere other than where it was. Then all they needed was an airfield at a similar altitude to its home base and they got it to land at their airfield, nice as you please and thank you for the donation of millions of dollars of military hardware.
