An Arizona woman has been sentenced to 8.5 years in federal prison for participating in a fraud scheme that helped give remote jobs to North Korean information technology specialists at over 300 companies in the United States, the Department of Justice announced Thursday.

The alleged scheme generated more than $17 million in revenue for the 50-year-old defendant, Christina Chapman, and North Korea, the department said in a statement. The remote North Korean workers posed as U.S. citizens and residents to enter various companies.
