Our work on <a href="https://insinuator.net/2015/07/redstar-os-watermarking/">RedStar OS from last year</a> revealed a nasty watermarking mechanism that can be used to track the origin and distribution path of media files in North Korea. We have seen some interesting dead code in some of RedStar’s binaries that indicated a more sophisticated mechanism to control the distribution of media files. We got hands on a Tablet PC called “Ul-lim” that implemented this advanced control mechanism.</p>
