The Wall Street Journal used leaked browser histories, emails, calendars, screen recordings, interviews, and previously unseen videos to trace a North Korean remote-worker cell that infiltrated at least eight U.S. companies within months. Thousands of DPRK operatives reportedly use stolen identities, AI tools, and U.S.-based accomplices to secure remote jobs and send earnings to the regime. WSJ estimates the wider operation generates about $800 million a year for Pyongyang.
