Researchers present operation North Korean system
Two German security researchers have the North Korean Red Star operating system under scrutiny. The Fedora 11 Linux-based system tracks every change that bring users into the holes and providing files of a ‘watermark’.
The two researchers presented their research at the Chaos Communication Congress, which takes place at this time in Hamburg. The survey shows that North Korea ‘every aspect of the system wants to keep in his own hands. ” In 2010 there were already reports out that the country was working on its own operating system. The system is based on the Linux distribution Fedora 11 and uses a kernel from 2011. The design has the appearance of OS X, while the version that came out in 2010 seemed more like Windows XP. There were indications that the system is made by ten developers.
The researchers, who for the German IT security company ERNW work, argue that the operating system whenever a new file provides a ‘watermark’, without the user noticing. This would be possible to track where a particular file has come from and who has opened. There would also run a daemon on the system that monitors the md5 hashes of critical files. Once a veranderng occurs, the computer immediately restarts.
In addition, the system would be equipped with a personal firewall and antivirus software, which retrieves new definitions from a server in North Korea. There could be even used his own version of AES encryption by the system. In the estimation of the researchers, the system is the result of an effort North Korean citizens to provide a control system with several basic functions and extensive monitoring capabilities. There would be no indication that the system could be used for Internet attacks.
