Justice Department charged four North Koreans with posing as IT workers to steal U.S. companies money, it said Monday.

“These schemes target and steal from U.S. companies and are designed to evade sanctions and fund the North Korean regime’s illicit programs, including its weapons programs,” Assistant Attorney General John Eisenberg, the head of the Justice Department’s National Security Division, said in a statement.

Two indictments, one arrest, and other actions across 16 states puts a dent in the illicit remote work schemes targeting US companies.
