"We can tell you that there are thousands of North Korean IT workers that are part of this," spokeswoman Rebecca Wu said.
The IT workers generated millions of dollars and, in some cases, infiltrated computer networks and stole information from the companies that hired them, authorities said. Officials didn't reveal the names of the companies that hired the workers or how federal authorities became aware of the scheme.
North Korea has used a variety of criminal schemes to fund its regime.
In 2016, four Chinese nationals and a trading company were charged in the U.S. with using front companies to evade sanctions targeting North Korea’s nuclear weapons and ballistics initiatives.
In February, United Nations experts said that North Korean hackers working for the government stole record-breaking virtual assets last year estimated to be worth between $630 million and more than $1 billion.
