Hacked Oil Tankers Approached US Coast, Prompting Federal Response

US authorities have responded to a cybersecurity incident involving several oil tankers whose onboard networks were compromised as they headed toward the US coast. According to reporting, the FBI and Coast Guard boarded the vessels as part of an investigation into the intrusions.

The attack was not merely a data breach — in at least one case, the hackers interfered with a tanker’s navigation and propulsion systems, raising serious questions about the vulnerability of shipboard industrial control networks. Such interference can directly threaten a vessel’s ability to maneuver safely.

Federal investigators are now working to determine how the networks were accessed and whether the incidents are linked to a broader campaign. The case underscores growing concerns about cyber threats to critical maritime infrastructure, where operational technology is increasingly connected.

The incident adds to a pattern of cyberattacks targeting transportation and industrial systems, highlighting the need for stronger safeguards across both public and private fleets.
