A hacker group has disrupted the communication networks of ships belonging to two major Iranian shipping companies sanctioned by the US.

The group, called Lab Dookhtegan or “Read My Lips”, said it has disrupted the communication networks of 116 ships and therefore, severed the ships' connections to each other, their ports, and external communication channels, according to a report by Iran International.

The attack, the report said, was timed to coincide with US military operations against the Iran-backed Yemeni Houthis.

“As part of this operation, we targeted the communication network 50 ships belonging to the National Iranian Tanker Company (NITC) and 66 ships belonging to the Islamic Republic of Iran Shipping Lines (IRISL),” the report added.

The ships belong to two major Iranian companies sanctioned by the US Department of the Treasury, the United Kingdom, and the European Union.

Iran's Revolutionary Guards Corps (IRGC) have tightened their grip on the country's oil industry and control up to half the exports that generate most of Tehran's revenue and fund its proxies across the Middle East, according to Reuters.

All aspects of the oil business have come under the growing influence of the IRGC, from the shadow fleet of tankers that secretively ship sanctioned crude, to logistics and the front companies selling the oil, mostly to China, according to more than a dozen people interviewed by Reuters.

By disrupting ship communications, Lab Dookhtegan said on Tuesday it has significantly hindered operations, adding that full restoration of the affected systems could take weeks.

“Ship personnel can no longer communicate with one another, and their connection to the ports and outside world has been severed,” Iran International said.

US President Donald Trump's administration is considering a plan to stop and inspect Iranian oil tankers at sea under an international accord aimed at countering the spread of weapons of mass destruction, sources familiar with the matter told Reuters.

Trump has vowed to restore “maximum pressure” campaign to isolate Iran from the global economy and drive its oil exports to zero, in order to stop the country from obtaining a nuclear weapon.

Lab Dookhtegan said the attack coincided with its sixth anniversary and aims to demonstrate the scale and depth of its cooperation with individuals within the Iranian regime.

The group is known for previous cyber activities against Iran’s military and intelligence operations.

In July 2022, the group revealed the identity of IRGC-affiliated hackers who exploited European, Australian and US individuals and institutions in order to carry out ransomware activities.

CIA Director John Ratcliffe told skeptical US lawmakers that American military strikes destroyed Iran's lone metal conversion facility and in the process delivered a monumental setback to Tehran’s nuclear program that would take years to overcome, a US official said Sunday.

The official, who spoke on the condition of anonymity to discuss the sensitive intelligence, said Ratcliffe laid out the importance of the strikes on the metal conversion facility during a classified hearing for US lawmakers last week.

Details about the private briefings surfaced as President Donald Trump and his administration keep pushing back on questions from Democratic lawmakers and others about how far Iran was set back by the strikes before last Tuesday’s ceasefire with Israel took hold.

“It was obliterating like nobody’s ever seen before,” Trump said in an interview on Fox News Channel’s “Sunday Morning Futures.” “And that meant the end to their nuclear ambitions, at least for a period of time.”

Ratcliffe also told lawmakers that the intelligence community assessed the vast majority of Iran's amassed enriched uranium likely remains buried under the rubble at Isfahan and Fordo, two of the three key nuclear facilities targeted by US strikes.

But even if the uranium remains intact, the loss of its metal conversion facility effectively has taken away Tehran's ability to build a bomb for years to come, the official said.

Rafael Grossi, head of the International Atomic Energy Agency, said Sunday on CBS' “Face the Nation” that the three Iranian sites with “capabilities in terms of treatment, conversion and enrichment of uranium have been destroyed to an important degree.”

But, he added, “some is still standing” and that because capabilities remain, “if they so wish, they will be able to start doing this again.” He said assessing the full damage comes down to Iran allowing in inspectors.

"Frankly speaking, one cannot claim that everything has disappeared, and there is nothing there," Grossi said.

Trump has insisted from just hours after three key targets were struck by US bunker-buster bombs and Tomahawk missiles that Iran's nuclear program was “obliterated.”

His defense secretary, Pete Hegseth, has said they were “destroyed.” A preliminary report issued by the US Defense Intelligence Agency, meanwhile, said the strikes did significant damage to the Fordo, Natanz and Isfahan sites, but did not totally destroy the facilities.

As a result of Israeli and US strikes, Grossi says that “it is clear that there has been severe damage, but it’s not total damage." Israel claims it has set back Iran’s nuclear program by “many years.”

The metal conversion facility that Ratcliffe said was destroyed was located at the Isfahan nuclear facility. The process of transforming enriched uranium gas into dense metal, or metallization, is a key step in building the explosive core of a bomb.

Secretary of State Marco Rubio in comments at the NATO summit last week also suggested that it was likely the US strikes had destroyed the metal conversion facility.

“You can’t do a nuclear weapon without a conversion facility," Rubio said. "We can’t even find where it is, where it used to be on the map. You can’t even find where it used to be because the whole thing is just blackened out. It’s gone. It’s wiped out.”

The CIA director also stressed to lawmakers during the congressional briefing that Iran’s air defense was shattered during the 12-day assault. As a result, any attempt by Iran to rebuild its nuclear program could now easily be thwarted by Israeli strikes that Iran currently has little wherewithal to defend against, the official said.

Ratcliffe's briefing to lawmakers on the US findings appeared to mesh with some of Israeli officials' battle damage assessments.

Israeli officials have determined that Iran's ability to enrich uranium to a weapons-grade level was neutralized for a prolonged period, according to a senior Israeli military official who was not authorized to talk publicly about the matter.

Tehran's nuclear program also was significantly damaged by the strikes killing key scientists, damage to Iran's missile production industry and the battering of Iran's aerial defense system, according to the Israeli's assessment.

Grossi, and some Democrats, note that Iran still has the know-how.

“You cannot undo the knowledge that you have or the capacities that you have,” Grossi said, emphasizing the need to come to a diplomatic deal on the country's nuclear program.
