On November 4, 2026, the US Treasury imposed sanctions on an India-based network accused of providing fraudulent ship registrations to Iran's shadow fleet. This network allegedly misrepresented maritime authorities and issued false documentation, enabling vessels transporting Iranian petroleum to evade sanctions. Windward reported that 278 Iranian-linked ships were identified using fraudulent flags from 23 registries between August 6 and November 5, with Nicaragua and Anguilla being the most common. The fraudulent activities have raised concerns about vessel safety and regulatory oversight, as these ships may operate without valid insurance, exposing coastal states to financial risks. The US Treasury's Office of Foreign Assets Control (OFAC) issued an alert highlighting the risks associated with these fraudulent registrations, urging maritime service providers to conduct enhanced due diligence.
