Iran's Threats On U.s. Soil: Sleeper Cells, Lone Wolves, Cyberattacks And Eerie Numbers Code

With U.S. and Israeli forces continuing violative strikes connected Iran, national counterterrorism authorites are informing that nan hopeless theocracy could motorboat retaliatory strikes connected American ungraded utilizing sleeper cells, affiliated Iranian violent groups, lone wolf sympathizers aliases targeted cyberattacks.

Within days of nan sidesplitting of Iranian Supreme Leader Ayatollah Ali Khamenei connected Feb. 28, cryptic messages were broadcast globally connected a caller shortwave power frequency.

“Tavajjoh! Tavajjoh!” nan connection began, utilizing nan Persian connection for “attention.” The eerie antheral sound past publication a seemingly random drawstring of numbers.

The monotone transmission recalled nan mode successful which deep-cover Cold War spies for nan KGB and CIA erstwhile received orders. Using a typical encryption code, nan operatives could construe nan numerals into a readable message. Although messages from alleged number stations person been broadcast for decades, they are now little prevalent successful nan integer encryption age.

Still, national authorities warned section rule enforcement that they had detected a caller broadcast of a apt encoded series that could beryllium “an operational trigger” for “sleeper assets” perchance connected U.S. soil.

Although counterterrorism investigators person truthful acold recovered nary reliable circumstantial threat, a memo to constabulary agencies, first reported by ABC News, calls for section rule enforcement to beryllium connected heightened watch. The alert describes nan “preliminary signals analysis” of nan transmission, “likely of Iranian origin,” that was relayed crossed aggregate countries and intended for “clandestine recipients” who person nan encryption key.

“Sleeper cells person ever been a interest erstwhile it comes to Iranians and their proxies,” said Horace Frank, erstwhile caput of counterterrorism for nan Los Angeles constabulary and a retired adjunct chief. “This isn’t new, but fixed nan situation, immoderate of their proxies are emotion a batch much desperate.”

The FBI and nan Department of Homeland Security person been connected a warfare footing since Operation Epic Fury launched Feb. 28.

During President Biden’s term, nan Department of Homeland Security issued a threat appraisal saying, “Iran relies connected individuals pinch pre-existing entree to nan United States for surveillance and lethal plotting.”

Beyond nan thought of a deep-cover sleeper compartment threat, Iran has many times tried to prosecute assassins to termination U.S. officials.

After a U.S. airstrike against Iranian Gen. Qassem Suleimani successful 2020, Iran sought to termination former Secretary of State Mike Pompeo and erstwhile nationalist information advisor John Bolton to avenge nan general’s death. The Department of Justice charged Shahram Poursafi, a personnel of Iran’s Islamic Revolutionary Guard Corps, pinch trying to prosecute group to assassinate Bolton, a erstwhile apical charismatic successful nan Trump White House, betwixt October 2021 and April 2022 successful Washington and Maryland successful speech for $300,000. He remains a fugitive.

On Friday, Asif Raza Merchant was convicted successful a 2024 murder-for-hire crippled targeting President Trump and others, and attempting to perpetrate an enactment of coercion transcending nationalist boundaries. Pakistani autochthonal Merchant was recruited successful Karachi successful 2022 aliases early 2023, erstwhile he received training successful tradecraft, including countersurveillance by nan Islamic Revolutionary Guard Corps, prosecutors said. Merchant testified that successful 2024, he was sent to enlistee “Mafia” members to bargain documents, shape a protestation and put nan murders, but nan deed men turned retired to beryllium national agents.

In November 2024, nan Justice Department charged Farhad Shakeri — an Afghan nationalist domiciled successful Tehran — successful a abstracted plot. Authorities said he had besides been tasked by nan Revolutionary Guard pinch hiring personification to assassinate Trump.

Since nan Sept. 11 violent attacks, nan Los Angeles Police Department has attempted to hole for each mode of threats — instrumentality gun-based thoroughfare attacks; substance bombs pinch secondary explosives intended to termination first responders, and moreover radiation-laced soiled bombs. Using information lessons learned successful nan Middle East, nan LAPD moreover makes vehicles carrying Hollywood stars to nan Oscars zigzag astir actual barriers, while snipers pinch .50-caliber rifles support their eyes peeled for imaginable threats.

“We are astatine a heightened level of awareness,” Chief Jim McDonnell said. “Lone wolves successful our acquisition person been our concern.” Such attackers whitethorn beryllium inspired by talk successful nan Middle East, and spot themselves arsenic acting for nan cause.

“We person immoderate awesome partnerships pinch our section and national agencies,” erstwhile it comes to counterterrorism, McDonnell said. But historically, arsenic overmuch arsenic intelligence pays off, nan main said it is nan eyes and ears of nan nationalist that often present nan captious tip.

Those of Iranian descent number much than 700,000 successful Southern California, nan largest azygous organization extracurricular Iran. McDonnell said that brings heightened awareness.

Even arsenic nan LAPD and different agencies person thwarted respective lone wolf plots, nan nation’s worst violent onslaught since 9/11 unfolded successful San Bernardino. Restaurant inspector Syed Rizwan Farook, a U.S. citizen, and his Pakistani-born wife, Tashfeen Malik, walked into his San Bernardino County worker vacation statement pinch military-style battle rifles and changeable much than 30 people, sidesplitting 14 successful 2015.

The utmost violence, apparently inspired by jihadi propaganda online, thrust nan metropolis of San Bernardino into nan world spotlight.

For homeland information analysts, nan San Bernardino onslaught was a wake-up call. At nan time, they were still intensely focused connected preventing terrorists trained successful overseas lands from infiltrating America’s porous borders — arsenic nan 9/11 hijackers had. Now they were confronted pinch nan sedate threat that American citizens were being radicalized online.

Farook was raised successful Riverside. Malik was calved successful Pakistan and had lived astir of her life successful Saudi Arabia. They met online, married, had a 6-month-old girl, and lived successful Redlands. They had nary evident links to world violent networks — until Malik pledged allegiance to nan leader of nan extremist group Islamic State connected Facebook soon earlier nan attack.

Within a time of nan Iranian activity being targeted and killed, 53-year-old Ndiaga Diagne donned a hoodie emblazoned pinch nan words “Property of Allah” and a T-shirt stamped pinch an Iranian emblem creation and group astir sidesplitting 3 group and wounding 13 connected Austin’s celebrated barroom portion earlier being fatally changeable by constabulary successful Texas. Investigators are still looking into nan motive, including a “nexus to terrorism.”

Counterterrorism experts besides pass location is simply a threat from alleged proxies — those associated pinch nan Iranian government, including militants linked to Hezbollah successful Lebanon and nan Houthi activity successful Yemen. A Rand report, Hezbollah’s Networks successful Latin America, found that nan militant group had a sizeable web that was progressive successful nan Southern Hemisphere.

Frank, nan erstwhile constabulary official, said those proxies person traditionally utilized California arsenic a fertile guidelines for financing and person avoided different activities here. However, fixed nan subject threat Iran now faces, that could change.

In 2023, 2 Iranian nationals connected a U.S. information watch database were apprehended astatine nan Texas-Mexico border, stoking information concerns. After U.S.-Israeli strikes connected Iran’s atomic infrastructure past year, Customs & Border Patrol Commissioner Rodney Scott warned that “thousands of Iranian nationals person been documented entering nan United States illegally” betwixt 2022 and 2025. Countless much were astir apt “got-a-ways,” he said.

But immoderate experts opportunity Iranians pinch authorities ties don’t request to consequence separator crossings and person entree to clone identities. They statement that authorities successful São Paulo unmasked a hub for Iranian document-forging networks.

U.S. counterterrorism authorities person agelong watched nan cyber threat from Iranian-backed hackers. In caller years, those tied to nan authorities person been seen testing vulnerabilities successful U.S. systems and targeting h2o proviso facilities. But cybersecurity experts opportunity that opening nan greeting of Feb. 28, erstwhile nan strikes began, Iran’s disposable net connectivity dropped to betwixt 1% and 4%.

Joint Chiefs of Staff Chairman Gen. Dan Caine said U.S. Cyber Command was progressive successful “coordinated abstraction and cyber operations [that] efficaciously disrupted communications and sensor networks … leaving nan adversary without nan expertise to see, coordinate aliases respond effectively.”
