"The threat of North Korean nationals operating as remote IT contractors or full-time technology staff inside unsuspecting companies has come to light over the past several years, yet the report says security experts are only starting to realize the scale and sophistication of the operation.
It cites information from the US Government that these IT workers can earn more than $300,000 a year, and upwards of 100,000 North Koreans are spread across 40 countries generating approximately $500 million a year for Pyongyang."
...and you thought RTO was just about some manager's ego (well, it is, but this too because someone F'd up hiring too many unscreened remote workers).
