Security Firm Warns Of Crypto Scam Targeting Ships Near Strait Of Hormuz

The Strait of Hormuz, a critical maritime chokepoint in the Gulf region, has become the centre of a new wave of fraudulent activity in which scammers are impersonating Iranian authorities to extort stranded shipping operators. The fraudulent scheme involves demands for cryptocurrency payments in exchange for supposed “clearance” or safe passage through the waterway.

According to a warning issued by Greek maritime risk management firm MARISKS, unknown actors have been contacting shipping companies and claiming to represent Iranian authorities. These messages reportedly demand transit fees paid in Bitcoin or Tether, presenting them as mandatory charges for vessels seeking to pass through the strait. The firm has clearly stated that these communications are not legitimate.

MARISKS emphasised in its alert that the messages are a scam and have no connection to official Iranian government channels. The warning comes amid growing concern for shipping companies, as hundreds of vessels and approximately 20,000 seafarers are reportedly stranded in the Gulf region due to ongoing disruptions in maritime movement through the Strait of Hormuz.

The broader situation in the region has been shaped by heightened geopolitical tensions. Shipping traffic through the strait has been severely affected since late February 2026, following coordinated military strikes by the United States and Israel on Iranian targets under an operation referred to as “Operation Epic Fury.” The strikes reportedly hit military facilities, nuclear infrastructure, and leadership sites, triggering a sharp escalation in regional instability.

The disruption has had significant consequences for global energy flows, as the Strait of Hormuz traditionally handles around 20% of the world’s seaborne oil trade and a similar share of liquefied natural gas shipments. Since the escalation, tanker traffic has reportedly fallen by nearly 70%, underscoring the scale of disruption to international supply chains and energy markets.

Amid shifting developments, Iran has at times announced temporary openings of commercial passage during ceasefire discussions, only to reverse such decisions amid renewed restrictions and naval blockades. In this volatile environment, Tehran has also reportedly proposed official transit tolls for vessels using the strait, a detail that fraudsters appear to be exploiting to make their extortion attempts appear more credible. Shipping companies have been urged to verify all communications through official channels before making any payments or taking action.
