Iran Threat Background Image

The Iran Threat

The Iranian regime presents a threat from many angles: Cyber. Foreign intelligence. Terrorism.

Threats from the Iranian regime and its terrorist partners can reach across the globe. The FBI is committed to identifying and disrupting all Iranian intelligence and military operations that threaten American citizens or our nation's security and critical infrastructure.

Working with our intelligence and law enforcement partners worldwide, the FBI has countered a diverse set of threats directed by the Iranian regime, including attempted terrorist attacks and kidnappings, espionage and foreign influence operations, cyber attacks, sanctions evasion, and illicit procurement of sensitive technology to support Iran’s military capability and nuclear program.

The Iranian regime has used repressive tactics in its wrongful detention of Americans in Iran on unsubstantiated criminal charges. The Iranian regime has also exported its repression through its harassment and lethal targeting of Iranian dissidents worldwide, including Americans living in the United States.

The FBI will continue to work diligently to thwart Iran’s violent agenda and use all available authorities to investigate criminal actions directed by the Iranian regime and its terrorist partners like Lebanese Hizballah, including any threats to current or former U.S. officials.

“In the summer of 2021, hackers sponsored by the Iranian government tried to conduct one of the most despicable cyberattacks I’ve seen...when they decided to go after Boston Children’s Hospital. ...Our folks got the hospital’s team the information they needed to stop the danger right away.”
