This makes AIS much harder to spoof without being caught. Someone wanting to cause massive disruption and get away with it would be much more likely to be successful by making a single mayday call on channel 16. That seems to happen a couple times a year - far more frequently than any know cases of AIS spoofing.
Agreed.. As far as AIS goes, someone *might* be able to have some fun over-riding an individual ships' AIS transmission to show them slightly off-track one way or the other - enough to cause a collision with someone else in a narrow traffic lane, in fog, but then in those conditions you'd think people would be using radar in preference to AIS.

I think the take-home message is that, yes, it's possible to temporarily "spoof" AIS - but it's a totally pointless exercise. The "researchers" would have far more success (with the same effect on AIS transmissions BTW) by tampering with GPS.
