Advent of always-on satellite connections has exposed shipping to hacking attacks
Potential attackers can take advantage of poor security hygiene on board and the poor security of protocols and systems provided by maritime product vendors.
For instance, the operational technology (OT) systems that are used to control the steering gear, engines, ballast pumps, and so on, communicate using NMEA 0183 messages. However, there is no message authentication, encryption, or validation of these messages, and they are in plain text.
Munro went on to explain:
“All we need to do is man in the middle and modify the data. This isn’t GPS spoofing, which is well known and easy to detect, this is injecting small errors to force a ship slowly and insidiously off course.”
In this case, the ship was subtly off course well before it struck the bridge support. We know that it lost power at least twice as it was approaching the bridge, meaning that it would lose rudder control.
Also unrelated, there do appear to be flashes at certain locations on the bridge in places that would facilitate its collapse. Does any of this mean anything? All I know is that it does raise questions. If a ship can be subtly aligned off course to strike bridges and shut down shipping lanes, that is obviously a major problem.
Was this an attack? Draw your own conclusions. As time goes on and more information seeps out, we may eventually know one way or another. In any case, we do know that a cyber backdoor exists, and it needs to be slammed shut now.
