“Ghost” ships: the “spoofing” of ships in the Strait of Hormuz threatens to increase chaos in the area

“Now we are starting to see ships turning off their systems or they use zombie or random IDs” Ami Daniel, CEO of Windward, a maritime intelligence data provider, said in an interview Tuesday.

In the weeks following the US and Israeli attack on Iran in late February, Iranian exports remained “uninterrupted” and “they almost didn’t need to leave the radar,” said Daniel.

But in the past 24 hours, more ships appear to be manipulating the global system meant to monitor ship activity and traffic, suggesting that some vessels linked to Iran They are being “a little more cautious”he stated.

Under international maritime law, most large commercial vessels must travel with a transponder what automatically transmits the name of the ship, its location, route and other identifying information. This includes a nine digit number with a country code, which serves as a fingerprint for a ship.

Some experts say ships in Middle Eastern waters now trying to hide their locations or falsify information are using perfected methods by Russian “shadow fleet” ships evading sanctions related to the 2022 invasion of Ukraine.

“The tankers of the shadow fleet have been experimenting with stateless identification numbers,” said John CK Daly, a nonresident fellow at the Central Asia and Caucasus Institute in Washington, who has been tracking Russian shadow ships. “What the Russians have been doing is to alter the numbers“.

When a ship makes “spoofing” (impersonation of your nautical identity) as this practice is known, your captain may enter a false origin or destination or you can pretend you’re piloting another ship entirely. Ships can also temporarily turn off your transpondersappearing to disappear in one place and reappear in another, sometimes with altered data.

This approach has allowed Russia to maintain its energy exports and finance its wargenerating up to 100 billion dollars a year.

Experts say ships linked to Iran appear to They are using similar methods now. Some ships have turned off their radars, while sanctioned and false flag vessels they seem to be still activenoted a Windward report on Tuesday.

“Under previous enforcement frameworks, including the blockade of Venezuela in December, sanctioned and stateless tankers were the main targets for interception” the report said. “The continued movement of similar vessel profiles indicates that operators are testing the practical limits of the application in real time.”

By manipulating the global system intended to clarify the movements of ships, the so-called ghost or shadow ships can increase confusion about the status of the Strait of Hormuz, even if in the end they cannot break the US blockade.

“Right now, the strait is a contested information environment,” said Erik Bethel, a partner at Mare Liberum, a maritime technology venture capital fund.

Tricks to avoid detection can make it difficult for the Navy to identify ships for interception. “A blockade is only as strong as the intelligence behind the interceptions,” Bethel said.

The maritime system is complex. A ship can be owned by one country, leased to another and travel under the flag of convenience of a third country, Bethel explained. That makes determining who is really behind any trip difficult. a “really difficult task.”

Maritime intelligence companies and militaries use a number of sources to piece together information about ships, including optical satellites, radar satellites and radio frequencies. They also collect information transmitted by sailors, sometimes unknowingly, through their own personal technology, such as Fitbits and cell phones.

Still, whatever tricks they employ, the ships off Iran They could only go so far. It is difficult to get out into the open ocean through a waterway as narrow as the Strait of Hormuz. without being detected.

A US official said that more than 12 US military ships They were stationed in international waters in the Gulf of Oman. And on Tuesday, US Central Command reported that six merchant ships had complied with radio instructions of American forces to turn around and re-enter Iranian ports.

“My expectation is that the US Navy can be stationed in the Gulf of Oman,” said Windward’s Daniel. “I don’t think there is a way to break the blockade.”
