[Noisebridge-discuss] Iran hacked US drone by spoofing GPS, jamming control signals

[Gopiballava Flaherty]

Remember what anti-replay protection on the nav data means: you are receiving data that appears valid except for some specific issues with it. You will then decide to do something like blow up something expensive, or land using inaccurate sensors, etc. 

You'd better be sure the data is actually invalid / messed with before discarding valid-ish data...

Don't forget the CYA aspect. "I know we lost a perfectly functional drone, but just imagine if the Iranians got one. It's worth losing a few to higher than expected multi-path looking like replay of old data..."

Thanks,
