North Korea-Linked Schemes to Obtain Employment in U.S. Tech Companies: What You Need to Know and How to Respond
During the past few years, operatives associated with the Democratic People’s Republic of Korea (North Korea or the DPRK) have reportedly infiltrated hundreds of U.S. companies by fraudulently posing as legitimate remote IT workers. The perpetrators, together with accomplices across multiple jurisdictions (including inside the U.S.), funnel wages back to North Korea in violation of economic sanctions, and in many cases steal company data, source code, and trade secrets. In a smaller subset of cases, after being discovered and terminated, perpetrators have released, or threatened to release, sensitive company data and attempted to extort ransom payments.
