## Feds board tanker mid-ocean
Coast Guard and FBI agents boarded a foreign-flagged oil tanker crossing the Atlantic on August 21 after detecting its network may have been compromised by a foreign actor.
## Specialized cyber teams deployed
A Coast Guard Cyber Protection Team and FBI Cyber Action Team examined the ship's operational and IT systems, working with the crew to remove the threat.

> Currently, there are no reports of operational disruptions, vessel instability, physical danger to crews, or environmental impacts
## Iranian media amplifies the story
The ship appears to be the VL Prosperity, a massive crude carrier bound for Galveston. Iranian state media reported the attack, though the U.S. hasn't attributed it to any actor.
## Attackers targeted engine systems
Iranian reports claim hackers penetrated engine-room systems on August 7, reducing cooling flow, increasing engine speed, and interfering with fuel systems during a 30-hour blackout.
## Tankers could become weapons
Modern oil tankers use internet-connected systems to control propulsion, navigation and cargo. A hostile state could theoretically hijack these systems and turn a vessel into a weapon against a port.
## Key takeaway

Modern oil tankers' internet-connected systems create vulnerabilities that could allow hostile actors to remotely control massive vessels.
