FBI Reports Cyberattacks on Two Tankers in US Waters

The FBI said in a statement that its investigators responded on August 21 and August 24, 2026, to reports of cyberattacks on the systems of two foreign flagged commercial tankers. Citing the Associated Press, Iran's ISNA news agency reported that a team of cybersecurity experts from multiple agencies boarded the vessels in US waters to assess potential damage to their technology and operational systems.

The FBI said there were no reports of operational disruption, vessel instability, physical danger to crew, or environmental impact, and that the crews of both ships cooperated with the ongoing investigation. No individual or group has been identified as responsible for the attacks. Bloomberg separately reported that the United States is investigating similar cyber threats that have targeted nearly 20 cargo vessels worldwide.
