The mystery angle shows up when you try to find any incidents of North Korean hackers actually doing anything. That could be construed as particularly ominous. Only the most elite hackers do their work without leaving behind any tracks, or evidence. Some have maintained that, because North Koreas Internet connections come from China, the North Korean cyberwarriors could be cleverly masquerading as Chinese hackers. However, after a decade, there should be some visible signs of North Korean hacking. Its highly unlikely that the North Korean hackers have been able to wander around the net without leaving some signs. While North Korea has produced some competent engineers, we know from decades of examining their work, that they dont produce super-scientists, or people capable of the kind of innovation that would enable North Korean cyberwarriors to remain undetected all these years.
So do the North Korean cyberwarriors exist, or are they a creation of South Korean intelligence agencies trying to obtain more money to upgrade government Information War defenses? North Korea probably has some personnel working on Internet issues, and Mirim College probably does train Internet engineers. North Korea probably has a unit devoted to Internet based warfare. But we know that North Korea has a lot of military units that are competent, in the same way robots are. The North Koreans picked this technique up from their Soviet teachers back in the 1950s. North Korea is something of a museum of Stalinist techniques. But its doubtful that their Internet experts are flexible and innovative enough to be a real threat. South Korea has to be wary because they have become more dependent on the web than another other on the planet, with exception of the United States. As in the past, if the north is to start any new kind of mischief, they will work it on South Korea first. So whatever the skill level of the North Korean hackers, they will attack South Korea first.
Where are the mysterious, elite North Korean hackers.? For over a decade, the South Korean media has been reporting on the cyberwar capabilities of North Korea. All of this revolves around activity at Mirm College, a North Korean school that, since the early 1990s, has been training, for want of a better term, computer hackers. The story, as leaked by South Korean intelligence organizations, is that a hundred cyberwar experts are graduated from Mirim College each year. North Korea is supposed to have, at present, a cyberwar unit of some 600 skilled hackers and Internet technicians. On the other hand, it more likely that those Mirim College grads are hard at work maintaining the government intranet, not plotting cyberwar against the south. Moreover, North Korea has been providing programming services to South Korean firms. Not a lot, but the work is competent, and cheap. So there is some software engineering capability north of the DMZ.
