"An oil tanker seized by U.S. forces off the coast of Venezuela this week has shone a light on a technique that experts say so-called dark-fleet ships frequently use to disguise their location. Known as spoofing, the method involves manipulating a ship's automatic identification system (AIS), a radio tracker that broadcasts its position and identifiers to other vessels and ports. Instead of broadcasting its real-time coordinates, a spoofing ship sends out a fake location."
"When it was seized, it was reportedly sailing under the flag of Guyana, although the Guyanese government has said it was not authorized to do so. U.S. officials have not disclosed how they found the tanker. But according to Windwarda large maritime data companyit is allgedly thought to have been part of dark fleet network of tankers that secretly move sanctioned oil around the world using deceptive tactics such as fake flags or AIS manipulation."
U.S. forces seized a large crude oil tanker off Venezuela that reportedly used AIS spoofing to disguise its location. The tanker previously faced sanctions for alleged smuggling and was sailing under an unauthorized flag claim. Spoofing manipulates the automatic identification system, broadcasting false coordinates instead of real-time positions. Dark-fleet networks employ deceptive tactics such as fake flags and AIS manipulation to move sanctioned oil globally. AIS is mandated for large ships, yet manipulation persists. Advanced visual-tracking and maritime-data analysis offer tools to expose and verify actual ship locations despite electronic deception.
