Hacking career

North Korea OS

In January 2015, Clark publicized the Red Star Operating System, which was the operating system of North Korea, one of the most secretive countries in the world. In 2013, the first images of the OS were publicized by former Google employee Will Scott, but Clark was the first to release the system in full. Research on the OS revealed it was designed to suppress all information available to users, instead opting for a state-sponsored system with only selectively available websites.
