Trend micro , firstly concentrated on hacking marinetraffc,com by generating fake AIS
NMEA messages and feeding them. Since " global monitoring" or the use of AIS over the
Internet is NOT imo approved, its an irrelevant excercise, but generates amusing data on marinetrsffic.com
Their second exercise , using a SDR to effectively generate there own AIS over the air messages , is also basically irrelevant, firstly since anyone can switch off AIS , effectively causing a ship to " disappear " is irrelevant
The second one , transmitting bogus data , again AiS makes no commitment that any information so transmitted is actually real ( see the course markers at the Americas Cup ) hence you always need to use other means to verify one source of nav data ( remember that one )
Fundamentally Trend appear clever ( this was a piece done for the hack a day conference ) but mis represent AIS as some sort of global
security monitoring
service, that's easily hack able ( shock horror drum roll ) where of course, AIS is nothing of the sort. Where authorities so inclined , merely cross referencing mmsi, callsign, name with other vessel reporting system like AMVER for example provides a easy achieve ability to defeat spoofing ( not to mention trying to call up, spoof ships on VHF )
This is the trouble with
software techie heads , out of their field of understanding
