**Deck**: U.S. authorities are investigating suspected cyberattacks on at least two foreign oil and LNG tankers that were hit while passing through the Strait of Gibraltar in August and later inspected in the Gulf of Mexico. Officials say the intrusions compromised the ships’ operational and IT systems.

Suspected hackers reached into the systems of at least two tankers carrying energy cargoes to the United States, prompting a joint investigation by U.S. agencies.

The vessels, foreign‑flagged oil and LNG tankers, were targeted in August as they transited the Strait of Gibraltar. After they reached the Gulf of Mexico, teams from the U.S. Coast Guard and the FBI boarded them for detailed inspections.

Officials say the attacks compromised both operational systems—which help run a ship’s equipment—and IT systems, which handle data and communications. They haven’t named the ships, the countries they sail under, or any suspected culprits.

Operational technology on modern tankers can include controls for navigation, cargo handling and engines. When those systems are affected, the risk extends beyond data theft to potential loss of control over the vessel itself.

The location of the initial compromise adds to the concern. The Strait of Gibraltar is a narrow maritime chokepoint linking the Atlantic and the Mediterranean. Much of the traffic from North Africa, the Middle East and Europe toward the U.S. Gulf Coast passes through this corridor.

For Washington, the case shows that cyber risk doesn’t stop at port gates. It follows ships along their routes and can touch the hardware that keeps energy trade moving.

Signals to watch now include any new U.S. Coast Guard or FBI advisories on cyber incidents at sea, updated reporting rules for shipping companies, and whether more operators disclose similar intrusions on tankers bound for U.S. ports.
