FBI confirms two Texas-bound oil tankers hit by hackers who disabled coms and put the engines into overdrive — and Iran is possibly to blame

Investigators found malicious cyber activity aboard both foreign-flagged vessels, and officials said no operational disruptions or environmental impacts were reported.

  • On Thursday, the FBI and Coast Guard confirmed they boarded two foreign-flagged oil tankers in the Gulf of Mexico last month after hackers breached the vessels' computer networks.
  • Investigators found malicious cyber activity aboard the VL Prosperity and Kohaku, both bound for Texas, raising concerns about compromised navigation and cargo control systems.
  • The 333-meter Prosperity, transporting 2.3 million barrels of oil, reportedly suffered engine room interference and lost communications for 30 hours during its transit through the Strait of Gibraltar.
  • Crews cooperated with specialized FBI and Coast Guard cyber teams during the investigation, with officials reporting no operational disruptions, vessel instability, or environmental damage.
  • CISA has characterized the attacks as "opportunistic" in nature, while U.S. authorities monitor nearly 20 vessels globally for similar cyber threats amid growing maritime security concerns.
