The short answer
Monica Elfriede Witt is a former United States Air Force counterintelligence officer who defected to Iran in August 2013 and is accused of providing classified national defence information to the Iranian government. She remains on the FBI's most wanted list, and in May 2026 the bureau increased the public reward for information that leads to her arrest.
Witt is believed to still be living inside Iran, possibly under a new identity and the protection of the Iranian Revolutionary Guard Corps (IRGC).
Background: Who is Monica Witt?
Witt served in the United States Air Force from 1997 to 2008. During that time she:
- Held high level security clearances.
- Trained as a Farsi linguist and counterintelligence specialist.
- Worked on sensitive operations targeting Iranian intelligence activity.
After leaving active duty she stayed in the intelligence world as a Department of Defence contractor before her career path took a sharp and very public turn.
The 2013 defection
In February 2012, Witt travelled to Iran to attend a conference billed as a discussion on US media bias. Iranian state television featured her on camera renouncing the United States. She returned to the US briefly, then in August 2013 made the move permanent and defected.
According to the federal indictment, once inside Iran she was given housing and computer equipment by the IRGC and began turning over classified information she had retained from her counterintelligence career.
The FBI charges
A federal grand jury in Washington DC indicted Witt in February 2019. The charges are serious:
- Conspiracy to deliver national defence information to representatives of the Iranian government.
- Delivery of national defence information to a foreign power, specifically the IRGC.
Among the most damaging allegations is that Witt disclosed the true name and covert mission of a US intelligence officer, along with details of an active classified Department of Defence programme.
Why the case is back in the news in May 2026
The FBI has refreshed its wanted notice and quietly raised the public reward for information that leads to her arrest. The bureau is also asking Iranian American community members to share what they know, anonymously if needed.
Two factors are driving the renewed push:
- Heightened US Iran tensions through the first half of 2026.
- New intelligence indicating Witt may have moved cities inside Iran in late 2025.
Why the Witt case still matters
The Witt file has become a teaching case inside US intelligence agencies. It reshaped how the Air Force, the FBI, and the Department of Defence vet, monitor, and re vet personnel who hold sensitive clearances after leaving active duty.
Insider threat programmes have expanded, continuous evaluation has replaced point in time background checks, and counterintelligence training now uses the Witt case as the prime example of how a single trusted insider can damage a network of foreign assets.

The takeaway
Monica Witt's story is a stark reminder that the most damaging breaches do not always come from outside hackers. A trained insider with a clearance and a grievance can do generational harm, and more than a decade after her defection, the United States is still trying to bring her home to face trial.
Monica Witt's Background
Monica Elfriede Witt is a former United States Air Force counterintelligence officer with a top secret clearance who later defected to Iran. The FBI alleges she disclosed classified information about US intelligence operations and helped Iranian cyber actors target her former colleagues.
The Charges Against Her
- Conspiracy to deliver national defense information to representatives of a foreign government.
- Delivering national defense information to representatives of a foreign government.
Both charges carry potential life sentences upon conviction.
Why She Remains on the Most Wanted List
Witt has been a fugitive since her 2019 indictment. The FBI continues to publicize her case to encourage tips from anyone who may have information about her whereabouts, particularly travelers who may have encountered her in Iran or third countries.
The Espionage Allegations in Detail
According to court filings, Witt provided Iran with information identifying US intelligence officers by name, role, and operational background. She is also alleged to have helped craft social engineering campaigns targeting her former colleagues' personal devices and online accounts.
How This Case Shaped Counterintelligence
- Heightened scrutiny of personnel who travel to or communicate with adversary countries.
- Expanded continuous vetting programs for cleared personnel.
- Greater investment in insider threat detection technology.
What the Reward Covers
The State Department's Rewards for Justice program offers up to several million dollars for information leading to her arrest. Anonymous tips can be submitted through secure channels operated by both the FBI and the State Department.
Why the Public Should Care
Insider espionage cases like Witt's illustrate how individual actions can compromise broad national security programs. They also underscore the importance of strong personnel security, mental health support for cleared workers, and exit interviews that take potential warning signs seriously.
