North Korea missile program funded by US IT workers?

 AP:

Thousands of information technology workers contracting with U.S. companies have for years secretly sent millions of dollars of their wages to North Korea for use in its ballistic missile program, FBI and Department of Justice officials said.

The Justice Department said Wednesday that IT workers dispatched and contracted by North Korea to work remotely with companies in St. Louis and elsewhere in the U.S. have been using false identities to get the jobs. The money they earned was funneled to the North Korean weapons program, FBI leaders said at a news conference in St. Louis.

Federal authorities announced the seizure of $1.5 million and 17 domain names as part of the investigation, which is ongoing.

Jay Greenberg, special agent in charge of the St. Louis FBI office, said any company that hired freelance IT workers “more than likely” hired someone participating in the scheme. An FBI spokeswoman said Thursday that the North Koreans contracted with companies across the U.S. and in some other countries.

“We can tell you that there are thousands of North Korea IT workers that are part of this,” spokeswoman Rebecca Wu said.

FBI officials said the scheme is so prevalent that companies must be extra vigilant in verifying whom they are hiring, including requiring interviewees to at least be seen via video.

“At a minimum, the FBI recommends that employers take additional proactive steps with remote IT workers to make it harder for bad actors to hide their identities," Greenberg said in a news release.

I don't understand why any US company would be contracting with North Korea.  I am surprised that those responsible for this have not been charged with some elements of treason.
