Wall Street Journal reporter Robert McMillan and FBI agent Joe Hooper recount the story of Christina Chapman, a Minnesota woman who is drawn into the world of laptop farming. She is struggling to make ends meet, living in a trailer without running water, and a job offer to be the US representative for an international company is a godsend. Laptop farms gained popularity in 2020 with the rise in remote work, allowing North Korean workers to evade sanctions, infiltrate American companies, and funnel money directly into North Korea’s weapons programs.

The hiring companies, many of which are high-profile, are unknowingly giving North Korea money and access to sensitive data.
