Christina Chapman, 50, an Arizona woman who pleaded guilty to charges connected to the global North Korean IT workers scheme, has been sentenced to 8.5 years in federal prison. According to court documents, Chapman helped North Korean workers fraudulently obtain remote-work jobs at U.S. companies. It is perpetrating fraud on American citizens, American companies, and American banks. If this happened to these big banks, to these Fortune 500, brand name, quintessential American companies, it can or is happening at your company. A North Korean defector who uses the alias “Kim Ji-min” previously told Fortune, via an interpreter, that Americans involved had “no idea” they were working with North Koreans.
