Re the AIS systems, both Class A and Class B 'can' have transmit disabled (either software or hardware) and continue to 'receive' AIS data from others. The quickest way to shut this mess down is seizure of vessels because the total number used for these exchanges is actually fairly small, and once the 'ownership' trail is unwound, most of them trace back to specific companies already under sanction.
Per the International Maritime Organization (IMO)-
Requires AIS on all ships of 300 gross tonnage (GT) or more on international voyages, cargo ships of 500 GT or more not on international voyages, and all passenger ships. AIS should be in operation when ships are underway or at anchor. I'll have to go find the law of the sea issue on seizure.

But under what legal authority can this seizure happen? Is it illegal I disable the AIS or just unsafe? Curious.
