In exchange, she disclosed classified information, including detailed information about US intelligence officials, using information to draft "target packages" against those intelligence community individuals, the indictment charges.
She left the Air Force in 2008 as a special agent assigned to the 2nd Field Investigations Squadron at Joint Base Andrews in Maryland just outside of Washington D.C., according to military records.
In one message she wrote that she might "do like (Edward) Snowden", the former USA intelligence contractor who in early June 2013 leaked thousands of documents on the operations of the National Security Agency.
Witt is still believed to be in Iran, which does not have an extradition treaty with the U.S.
Also charged are four Iranians who allegedly worked on behalf of the Quds. Witt said in communications obtained by investigators that she had difficulty getting over Iranian suspicions, despite embedding herself with members of the IRGC and appearing in anti-US propaganda videos.
The efforts included software to capture keystrokes and break into web cameras, as well as malware-infused attachments passed off as pornographic photos created to fool USA officials into letting Iranian hackers tunnel into their computer networks.
The indictment also alleges that Witt planned to go to Russian Federation in 2013 to contact WikiLeaks without disclosing her location.
The U.S. Treasury is also placing sanctions on the New Horizon Organization and Net Peygard, a company that associated the hacking of agents.
An FBI missing person poster from the time shows two pictures of Witt wearing a headscarf and saying she was last known to be travelling and working in southwest Asia.
WASHINGTON, DC - OCTOBER 04: Assistant U.S. Attorney General for National Security John C. Demers (2nd L), United States Attorney for the Western District of Pennsylvania Scott W. Brady (R), and FBI Deputy Assistant Director for Cyber Division Eric Welling (L) listen during a news conference to announce criminal charges on October 4, 2018 in Washington, DC. She also reportedly went overseas several times on counterintelligence missions.
She wrote Individual A that she wanted to put her Air Force training "to good use instead of evil".
During her time in the military, she had top secret clearance, the indictment says, which gave her access to intelligence materials that contained the real names of American sources and clandestine agents.
In 2012, after Witt travelled to Iran for a conference, the FBI warned her that she could be a targeted for recruitment by that country's government, and Witt told the bureau she would refuse to provide information about her military work, according to the indictment. "I am starting to get frustrated at the level of Iranian suspicion". Authorities said Mojtaba Masoumpour, Behzad Mesri, Hossein Parvar and Mohamad Paryar sought to install malware in the computers of Witt's former co-workers through fake social media accounts.
