The State Department is offering a $10 million reward for information leading to the capture of three Iranians, who it said have worked for tech companies linked to the Iranian Revolutionary Guards Corps.
The Iranians have been charged with trying to extort hundreds of thousands of dollars from organizations in the United States, Europe, Iran and Israel, including a domestic violence shelter, by hacking in to their computer systems, US officials said on Wednesday.
Other targets included local US governments, regional utilities in Mississippi and Indiana, accounting firms and a state lawyers' association, according to charges filed by the US Justice Department.
The defendants, named Mansour Ahmadi, Ahmad Khatibi and Amir Hossein Nikaein, are citizens of Iran who own or are employed by private technology companies in the country.
The Treasury Department also imposed sanctions on the three Iranians, as well as several other individuals and two organizations they said were part of Tehran's "malicious" cyber and ransomware activity.
“The government of Iran has created a safe haven where cybercriminals acting for personal gain flourish and defendants like these are able to hack and extort victims, including critical infrastructure providers,” said Matthew G. Olsen, the assistant attorney general of the Justice Department’s national security division.
The men remain at large in Iran, and prosecutors said they were highly unlikely to face trial in the United States. Officials said they hoped that by exposing the group, they might prevent future attacks.
