Recently several videos from recruiters on LinkedIn have gone viral. The videos appear to show recruiters conducting routine job interviews over a video call, but something is up with the candidates. Their faces are blurred, and they appear to be using some sort of a filter. After some strange interaction with the recruiter, they drop off the call. But these creepy videos are not isolated incidents – many recruiters are reporting that this has happened to them multiple times. Who are these candidates really? We expose the phenomenon of North Korean IT workers applying for remote tech jobs in the US, and how this has become a significant revenue raising scheme for Kim Jong Un’s regime.

And now, there is evidence that the scheme is expanding into Europe. This episode of The Documentary, comes to you from BBC Trending in-depth reporting on the world of social media.
