The government of South Korea has revealed that its cyber military command was hacked in September by injecting malicious codes into one of its main routing servers. Nearly 20,000 military computers were connected to the server at the time of attack; however, as the military intranet was not connected to the targeted server, it is unlikely that any data was stolen. At least that is the official line.
While the origin of the attack is as yet unknown, the finger of suspicion is pointing – as usual – north of the border. Alongside its much-publicised nuclear activity, North Korea has built up a formidable army of cyber warriors over the last twenty years. South Korea has countered this threat by establishing its own elite cyber defence force, though perhaps on this occasion, that defence had a few holes in it.
