Fraudsters Use Fake Bitcoin Transit Fees to Target Stranded Ships
Greek maritime risk firm MARISKS has warned that unknown actors are targeting global shipping companies with fraudulent payment demands, claiming to represent Iranian authorities and offering safe passage through the Strait of Hormuz in exchange for Bitcoin or Tether (USDT). The alerts come as tensions between the United States and Iran disrupt one of the world's most critical energy corridors, with military activity and shifting restrictions leaving hundreds of vessels stalled west of the passage and approximately 20,000 seafarers affected.
According to MARISKS, the messages instruct companies to submit vessel documentation for review by 'Iranian Security Services,' after which a transit fee would be set in Bitcoin or Tether. The senders claim ships would then receive clearance to pass without interference at a scheduled time. MARISKS said at least one vessel may have fallen victim to the scheme, linking the case to a ship that attempted to exit the strait and came under fire, though it could not confirm the connection. Reuters reporters could not verify which companies received the messages.
Iran Plans to Require Bitcoin Transit Fees
Earlier this month, Iran reportedly planned to require shipping companies to pay transit tolls in Bitcoin for vessels passing through the Strait of Hormuz, linking the move to one of the world's most critical energy corridors. The policy would issue payment requests before transit and require settlement in Bitcoin within a short window, designed to bypass traditional financial rails while maintaining control over access during a US–Iran ceasefire period. This official plan, while distinct from the fraudulent schemes, adds complexity and risk for shipping firms.
Security Risks and Legal Warnings
Security analysts warn that any such payment request carries legal and financial risk. Even if funds do not reach sanctioned entities, companies could face exposure under sanctions regimes tied to Iran. MARISKS emphasizes that all unsolicited payment demands claiming to be from Iranian authorities are fraudulent and not linked to Tehran. Shipping companies are advised to verify all communications through official channels, implement rigorous compliance checks, and avoid making any cryptocurrency payments without confirmed legitimacy. The ongoing military activities and temporary restrictions in the Strait of Hormuz continue to disrupt global shipping, making the industry particularly vulnerable to such targeted crypto scams.
