Zero Day details how North Korean IT workers allegedly hid their identities to win remote developer jobs at U.S. and foreign companies and route the earnings back to North Korea's weapons programs. The workers used fake web profiles, stolen identity documents, VPNs, U.S.-based proxy laptops, and paid stand-ins for interviews or video calls. The article links the scheme to Yanbian Silverstar Network Technology and Volasys Silver Star, and describes FBI actions that seized about $1.5 million and 17 domains used to market fraudulent worker fronts. Some workers also gained access to employer networks, creating insider-theft and extortion risk beyond sanctions evasion.
