Coast Guard inspects tankers after long comms loss
The U.S. Coast Guard and FBI confirmed in-person OT and IT inspections aboard two oil tankers on Aug. 21 and 24 after one vessel lost communications for more than 30 hours at sea. Investigators still have not publicly named an actor, and officials say they have seen no operational disruption, vessel instability, crew danger, or environmental harm.
Modern tankers can put navigation, propulsion, steering, cargo controls, and satellite communications on a shared onboard network behind a single firewall. If that network is disrupted, the ship can lose outside contact and see safety systems degraded without an attacker taking full command of the vessel.
The important shift is in the response model: federal teams can board and inspect the ship where it is, so a maritime cyber incident does not have to become a port closure. For operators, the durable exposure is the vessel’s own OT/IT stack, and the reporting still does not settle who was behind the intrusion.
US Coast Guard and FBI board oil tanker to investigate cyber attack
An oil tanker bound for Texas was boarded mid-voyage by the US Coast Guard and FBI last month, after its network may have been compromised by malicious hackers.
