Cyber warfare between the two Koreas

South Korea will push to increase its cyber warfare forces to more than 1,000 to enhance preparedness against an unprovoked attack, as this week's massive hacking highlighted the potential danger of cyber terror by North Korea. It may seem unlikely that impoverished North Korea, with one of the most restrictive Internet policies in the world, would have the ability to threaten affluent South Korea, a country considered a global leader in telecommunications. For several years, North Korea has poured money into science and technology.

The cyber attack against three major broadcasters and three banks, the biggest in two years, brought fresh attention to potential cyber attacks in South Korea, one of the world's most wired nations. Initial investigations found malware code used in the attack was from China. Authorities are focusing on possible links with North Korea as it has repeatedly threatened to launch various attacks on Seoul in light of new sanctions for its nuclear test and annual joint drills with the U.S. South Korea has about 400 personnel under the Cyber Command, a special unit launched in early 2010, but the military will increase the number of personnel to more than 1,000 in the wake of the growing cyber threat.
