Coast Guard and FBI boarded tankers due to cyberattacks. How big is the risk?

In August 2026, two energy tankers bound for Texas were targeted by cyberattacks, prompting U.S. Coast Guard and FBI intervention. One of the vessels, the VL Prosperity, a massive crude oil tanker, experienced a breach in its propulsion, navigation, and cargo systems, leading to a 30-hour communication blackout. Iranian media claimed responsibility, alleging hackers disrupted the ship’s engine systems. While the U.S. Coast Guard has not officially blamed Iran, they confirmed finding evidence of malicious cyber activity. The incident occurred near the Strait of Gibraltar, and the ship continued its journey to the U.S. after the attack. The Coast Guard and FBI conducted a thorough investigation on board, searching for malware and assessing the ship’s IT systems. This event highlights the vulnerability of critical infrastructure to cyber threats and the ongoing investigation into potential foreign involvement. QUESTION: How might increased cyberattacks on critical infrastructure impact global trade and security in the future?
