FBI and Coast Guard Board Suspected Compromised Oil Tankers Near U.S. Coast

Following intelligence that the vessels' computer networks might have been infiltrated, the Federal Bureau of Investigation and the U.S. Coast Guard boarded two oil tankers heading toward U.S. ports.

Officials say investigators are examining a cyber breach that seems to have penetrated at least one vessel's control systems to the extent of influencing its navigation and propulsion. Although the exact entry technique remains undisclosed, the case highlights mounting worries over maritime infrastructure's exposure to advanced hacking operations.

Both tankers, registered under foreign flags, were stopped in the Atlantic just before they would have crossed into U.S. territorial waters. Coast Guard teams carried out a detailed inspection, securing the ships and safeguarding electronic evidence for forensic review. The FBI’s cyber division heads the investigation, collaborating with maritime regulators and the vessel owners to gauge the breach’s extent.

Experts in cybersecurity point out that contemporary tankers depend on integrated networks for functions ranging from engine performance to cargo monitoring. Consequently, a successful hack can produce operational effects that vary from small system glitches to complete loss of steering. According to officials, the perpetrators altered the navigation suite, causing the ship to stray from its intended route until the crew regained manual control.

The event occurs as regulators and industry bodies ramp up initiatives to fortify the maritime supply chain against cyber threats. The International Maritime Organization has released guidance mandating cyber risk assessments, while the U.S. Department of Homeland Security has boosted funding for its Maritime Cybersecurity Program. Still, the intricate nature of shipboard networks and the worldwide scope of shipping keep full protection a continual challenge.

Officials have not disclosed any information on cargo loss or environmental effects, and there is no sign that the tankers incurred physical damage. The active probe aims to pinpoint the attackers, determine if the intrusion forms part of a larger campaign, and propose measures to avert similar events. As the FBI and Coast Guard maintain their joint effort, the case underscores that cyber threats have become a core issue for both national security and commercial maritime activities.
