More DDoS Attacks Could Rock Korea

If the culpable malware is not immediately eliminated, then the bots that launched distributed denial of service (DDoS) attack on July 7, 2010 could set off additional attacks, warned the Korean Communications Commission on July 8, 2010.

DDoS attacks are the cyber attacks that target particular systems by overloading them, whereas zombie PCs are the malware-infected PCs designed to trigger such attacks.

As per the National Police Agency, malware behind the massive DDoS attacks launched in 2009 on the US and local websites, which included Cheong Wa Dae, had not been addressed and it targeted the sites again that were targeted earlier in 2009.

Senior Police Officer, Jeong Seok-hwa, who was handling the cyber attack related investigations, said that in excess of 460 computers infected with malware attacked 25 websites, including the presidential Blue House of South Korea, on July 7, 2010 since they are designed to launch an attack on every July 7, as per the news published by Google on July 8, 2010.

Malware, or malicious computer codes, are used to launch the alleged denial of service attacks, wherein a several computers try to establish connection with a website simultaneously in a bid to overpower the server.

However, the attacks were extremely weak and there was no difficulty in accessing the websites, Jeong said. He further noted that majority of infected machines are located in South Korea while other are in Britain, China, US and Japan. The recent attack emerged around a month after two websites of the South Korean government were targeted with denial of service attack, which according to officials traced to China.

In the meantime, according to a South Korean government IT source, North Korea was responsible for the cyber attacks that took place on July 8, 2009. Moreover, the cyber center found in October 2009 that the attacks were launched from North Korea's IP Ministry, as per the National Police Agency.
