The U.S. Department of Justice charged three Iranian hackers for targeting various US victims, including a regional electric utility company in Indiana.

The indictment released on Wednesday shows that the DOJ is charging three Iranians, Mansour Ahmadi, Ahmad Khatibi, Amir Nikayin, for various international hacking schemes since October of 2020. Their victims include the United States, the United Kingdom, Israel, Iran and more.

They exploited vulnerabilities in network devices to take data, blocking victims from accessing their networks, then ransoming it back to them.

The DOJ says that the three targeted many different places, including small business, government agencies, nonprofit programs, and institutions. Notably targeting infrastructure centers like healthcare, utility, and transportation providers.

In 2021, the hackers targeted the network access for a New Jersey township. Recently, locking an accounting firm out of their systems and demanding $50,000 or they will sell the private data on the black market.

Regional electric utility companies have been targeted throughout the country, including one in Indiana.

Assistant Attorney General Matthew Olsen says that the hackers acted independently, although Iran is not helping.

“The Government of Iran has created a safe haven where cyber criminals acting for personal gain flourish and defendants like these are able to hack and extort victims, including critical infrastructure providers,” Assistant Attorney General Matthew Olsen said, “This indictment makes clear that even other Iranians are less safe because their own government fails to follow international norms and stop Iranian cyber criminals.”

All the hackers are still at large and are charged with conspiring to commit computer fraud, intentionally damaging a protected computer, and transmitting a demand in relation to damaging a protected computer. One hacker, Ahmadi, is additionally charged with intentionally damaging a protected computer. If caught and convicted, they would face 25 years in prison.
