The U.S. Coast Guard says it boarded at least one oil tanker in the Gulf of Mexico after suspected foreign hackers compromised the vessel’s network while it was headed to the United States. The reported incidents affected at least two tankers in August; one identified as VL Prosperity allegedly lost communications for about 30 hours, and reports cited possible interference with engine-speed controls and fuel and engine-oil systems. No CVE or malware family has been disclosed.
Why it matters: This is a high-impact maritime cyber incident because it potentially reached both shipboard information technology and operational technology that can affect navigation, propulsion, and port safety. Shipping, energy, and port operators should urgently review vessel-network segmentation, remote access, and incident-response coordination with maritime authorities.
