The first hack is pretty easy to do for anyone that can create NMEA data streams, not hard since the protocols are in the public domain. After all, if one is creating a legitimate piece of equipment that will work with an AIS system one has to create the proper data streams... and spoofing something with improper data at that point is an ethical decision, not a technical challenge. Kind of like the sport fisher I heard of that was broadcasting a Celebrity Cruise ship's MMSI offshore to keep other sport fisher's away. About 15 years ago I worked with a Navy gentleman who set up an AIS receiver off Norfolk and coupled a long range camera to it... and stated that over 50% of the signals being broadcast had errors. I'm not sure what the ratio might be now... but his impression was also that folks were not deliberately spoofing, but just had equipment that was never fully configured properly. The second link I believe requires the spoofing equipment to be close to the receiver being hacked... and is not practical outside of a "science fair" demonstration scenario. I think that stuff was discussed in another topic on this forum earlier....
