US Attorney General Merrick B. Garland said in a statement Monday that Abedini allegedly “supplied sensitive technology used by the Iranian military to kill three American service members.” He said the arrests demonstrated that the Justice Department will hold accountable those who enable the Iranian regime to target Americans and undermine the national security of the United States.

The drone attacked housing units at Tower 22, a small US outpost in Jordan near the border with Syria, during the early-morning hours of Jan. 28, according to the US Central Command.

Three Army Reserve soldiers killed in the attack were later identified as Staff Sergeant William Jerome Rivers, 46, of Carrollton, Ga.; Sergeant Kennedy Ladon Sanders, 24, of Waycross, Ga.; and Sergeant Breonna Moffett, 23, of Savannah, Ga. They were among some 350 troops stationed at the base to support a coalition mission aimed at defeating ISIS.

During a press conference Monday at the federal courthouse in Boston, Jodi Cohen, the special agent in charge of the FBI’s Boston office, said the arrests “disrupted an Iranian procurement network that we believe was directly involved in that horrific attack.”

Sadeghi and Abedini are accused of conspiring to illegally export sensitive technology from a semiconductor manufacturer headquartered in Massachusetts to Iran using a front company in Switzerland owned by Abedini, Cohen said.

Officials didn’t name the Massachusetts company. An affidavit filed in the case describes it only as a semiconductor company based in Norwood.

Sadeghi’s Linkedin page says he has worked at Analog Devices Inc.(ADI) for the past four years and is a technology group product marketing manager. He earned a PhD in electrical engineering at the University of Michigan, the page says.

A spokesperson for ADI, which is based in Norwood, said the company is cooperating with investigators.

“ADI takes its compliance obligations and role in national security very seriously,” a spokesperson said in an email Monday night. “We have cooperated fully with federal law enforcement and will continue to do so throughout the proceedings. ADI is committed to preventing unauthorized access to and misuse of our products and technology.”

At the press conference, Acting Massachusetts US Attorney Joshua Levy said the company was notified Monday of the leaked technology, and confirmed they are cooperating.

“We often cite hypothetical risk when we talk about the dangers of American technologies getting into dangerous hands,” Levy said . “Unfortunately, in this situation we are not speculating.”

FBI agents from the Terrorist Explosive Device Analytical Center recovered the drone used in the attack and traced the navigational system to a Tehran company owned by Abedini, who allegedly “has deep connections to the Iranian government, Iranian military, and to the Islamic Revolutionary Guard Corps,” according to Levy. The investigation then led to Sadeghi, officials said.

The complaint alleges that Sadeghi and Abedini conspired from January 2016 through this month to violate federal laws by exporting sensitive American technologies, according to Levy.

Sadeghi in 2015 helped to establish a Massachusetts technology company specializing in “fitness wearables,” or sensors that provide kinetic monitoring for fitness applications, according to the affidavit.

He later traveled to Iran to seek a $790,000 loan from the government’s Iranian National Elites Foundation. They loaned him a portion of the money and he created a sister company in Iran, the affidavit stated.

Shortly thereafter, Sadeghi allegedly entered into a contract with an Iranian company owned by Abedini, San’at Danesh Rahpooyan Aflak Co., or SDRA, which manufactures navigation systems for drones used by the IRGC.

On Aug. 27, 2019, Sadeghi introduced a colleague at the Norwood company to Abedini via email, saying Abedini owned a company in Switzerland and had interest in hardware, firmware, and software development, according to the affidavit.

On Sept. 2, 2019, the Abedini and the Norwood company signed a non-disclosure agreement. He ordered multiple components to be delivered to a Swiss university, the affidavit stated.

Abedini eventually established Illumove in Switzerland to disguise the transfer of goods to Iran, prosecutors said.

At least 14 times between March 2022 and April 2024, the Norwood company shared technology, including confidential data sheets, with Abedini who was believed to be in Iran, the affidavit said.

On April 18, 2023, the Norwood company advised Abedini that it had shipped about $15,000 worth of classified navigational control equipment to him in Switzerland, according to the affidavit.

Harakat Ansar Allah al-Awfiya, an Iran-aligned militia group which is part of the Islamic Resistance in Iraq, claimed responsibility for the attack. In June, the US State Department designated it a global terrorist group.

Iran has denied directing the attack, saying militia groups act on their own.

There were dozens of drone attacks on US troops in the Middle East in the months after the Oct. 7, 2023, attack on Israel by Hamas igniting the war in Gaza. But the January attack in Jordan marked the first one resulting in the deaths of American troops.

The arrests came after a home in Natick was raided by the FBI on Monday. Investigators were on the scene of 85 Woodland St., which property records show has been owned by Mohammad M. Sadeghi since 2016.

Agents with FBI written on their jackets came and went from the two-story house all day. A Natick police cruiser was parked in front of the driveway.

As a light rain fell in the early evening, a K9 unit entered the home, which has several windows. Several lights were on inside.

Residents in the area declined to comment to the Globe Monday evening.
