United States federal authorities have launched a formal investigation into cyberattacks targeting foreign energy tankers bound for American ports. The Federal Bureau of Investigation and the U.S. Coast Guard initiated probes after digital intrusions were detected on commercial vessels transporting oil and liquefied natural gas. Investigators boarded and inspected vessels, including the Liberian-flagged oil tanker VL Prosperity near Galveston, Texas, following network disruptions. Security reports indicated the vessel previously experienced a 30-hour communications blackout during transit near the Strait of Gibraltar, which impacted engine-room monitoring systems and fuel controls. Federal officials are examining whether foreign state-sponsored actors are utilizing advanced cyber warfare techniques to disrupt critical maritime supply chains and energy imports. The Department of Homeland Security is coordinating with international shipping companies to enhance cybersecurity protocols across vessels operating near United States territorial boundaries. No casualties, environmental spills, or immediate operational disruptions have been reported by officials during the ongoing investigation.
