The Department of Justice unveiled charges against an Iranian national on Thursday for a roughly five-year hacking spree that prosecutors say infiltrated the federal government and defense contractors, alleged cybercrimes that threatened the "national security" of the U.S.

United States Attorney for the Southern District of New York Damian Williams unsealed an indictment against Alireza Shafie Nasab, who they say was able to hack the U.S. Departments of Treasury and State and two New York-based companies, in addition to defense contractors and others.

Nasab and others allegedly carried out the attacks from sometime in 2016 through April 2021, prosecutors said.
