I'm not concerned about this kind of attack. Very few people live or work sufficiently close to the sea to be a potential target. Nobody can crash a container ship into the Pentagon. The damage a ship colision could do is probably mostly economic (a refinery, some docks, a bridge) and environmental (storage tanks near docks, a nuclear power station). It makes sense to do training for the shipping companies. Cyberattacks on shipping companies happend before, just not on ships. These attacks were ransomware. They don't intend to destroy their hacked assets, because no ransom would be paid, and they don't hack one system/target, they hack all of them at the same time.
