An ongoing disinformation campaign is causing a worldwide ship location and navigation system to falsely identify the whereabouts of western warships.
The Automatic Identification System (AIS) is designed to enhance safety at sea, but it looks like Russia is weaponizing it to make western navies appear more provocative than they really are. The results are "evidence" meant to embarrass the navies of NATO and Sweden, and falsified data meant to back up Russian claims of territorial violations at sea.
