Iran suspected of sending ships to map, operate against undersea internet cables
Four vessels linked to Iran have been tracked loitering over critical subsea internet cables in the Gulf of Oman and Persian Gulf, with some disabling their AIS transponders. The activity follows Iranian warnings of retaliation against U.S. and Israeli interests and coincides with heightened regional tension. Analysts assess the positioning as consistent with mapping or potential sabotage of the fiber-optic arteries that carry a significant portion of data traffic between Europe, Asia, and the Middle East. No cable damage has been reported.

Iran-linked ships loiter near Gulf undersea internet cables
Four vessels linked to Iran have been tracked loitering over critical subsea internet cables in the Gulf of Oman and Persian Gulf, with some disabling their AIS transponders. The activity follows Iranian warnings of retaliation against U.S. and Israeli interests and coincides with heightened regional tension. Analysts assess the positioning as consistent with mapping or potential sabotage of the fiber-optic arteries that carry a significant portion of data traffic between Europe, Asia, and the Middle East. No cable damage has been reported.
Why it matters
Undersea cables in the Gulf are chokepoints for global digital connectivity, linking three continents. Iran has previously threatened to disrupt maritime traffic and infrastructure in response to pressure over its nuclear program and regional proxies. The current maneuvers mirror tactics used in past grey-zone operations, raising concern that Tehran is rehearsing a deniable capability to degrade internet infrastructure without direct attribution.
What is confirmed
- Four Iran-linked ships have been tracked loitering over subsea internet cables in the Gulf of Oman.

- The cable routes affected carry a major portion of internet traffic between Europe, Asia, and the Middle East.
- Iran has recently issued warnings of retaliation against U.S. and Israeli interests in the region.
Still unconfirmed
- The ships are actively mapping cable vulnerabilities for future sabotage operations.
- Iran intends to coordinate cable disruption with Houthi attacks in the Red Sea.
What to watch next
- Confirmation of any cable damage or degradation in latency data
