As the most closed-off country on the planet, it shouldn’t come as a surprise that the North Korean government developed its own homegrown operating system that can be used to spy on its citizens.

Fueled by an unprecedented level of paranoia and a desire to keep its populace in line and closed off from the outside world, North Koreans outside of the government are completely shut off from the Internet. In its place? A nationwide intranet heavily controlled and monitored by the powers that be. And the mysterious operating system powering most of the computers in the country today? Red Star OS.

Recently, German researchers Florian Grunow and Niklaus Schiess managed to download a copy of Red Star OS, providing us with unprecedented details surrounding the country’s mysterious operating system. Based on a version of Linux called Fedora, Red Star OS, not surprisingly, leans heavily towards surveillance.

“We found that the features implemented in Red Star OS are the wet dream of a surveillance state dictator,” Grunow and Schiess explained. “It provides a set of surveillance features like the capabilities to watermark different types of files that can be used to track the distribution of documents and multi-media files.”

While that’s to be expected, what’s a little bit surprising is that Red Star OS looks remarkably like Apple’s OS X. You can check out a full 27 minute run down of how Red Star OS operates and what it looks like below, but for now, we’ve compiled a few photos which showcase the OS’ striking similarity to OS X.

Up first, during the installation process, we see a distinctly Aqua look and feel.

In this photo, you’ll note the presence of the Mac’s spinning beach ball

And here’s the desktop which looks exactly like OS X. As a interesting design detail, note how the Apple icon on the upper left hand corner of the menu bar is replaced with a North Korean Red Star.

Almost comically, when shifting the language to English, we see that the Finder has been renamed KFinder.

Here’s North Korean Quicktime.

And the System Preferences pane.

Ever wonder what kCal looks like?
