On April 6th, the Police Cyber Terror Response Unit's investigation results pointing the finger at North Korea in connection with the March 4th Denial of Service attacks on South Korea vindicate NKSIS's statements that it was a North Korean attack.
NKSIS carried reports on March 7th and 8th stating that the July 7th 2009 as well as this year's March 4th DDoS attacks had their origins in elaborate North Korean hacking attempts. This has been clarified by the police investigation.
The police statement put out on April 6th reported that "the attack structure and method, the transmission method of the virus code and its design all point to North Korea."
NKSIS reported that "a hundred thousand zombie PCs took part in this attack. Sixty of North Korea's elite hackers instigated it and its origins were spread over thirteen places in China. The North Korean hackers are skilled enough to confirm how deep the virus penetrated and even control its penetration."
The police report has confirmed our own inquiries. "As a result of seven months of investigations since last August, we have discovered that the IP addresses of the hackers originate in China. Many were camouflaged as zombie PCs, in order to check on the progress of the attacks."
The police are requesting joint international efforts to more precisely locate the hacker's location. As the police investigation proceeds the activities of the North Korean hacking outfit that launched the March 4th attacks will become clearer.
