South Korea has been on heightened alert against the threat of cyberattacks by North Korea after it conducted a nuclear test in January and a long-range rocket launch last month that led to new U.N. sanctions. North Korea denied the accusation. South Korea blamed the North for that attack. The internet address was identical to the one used in a 2013 cyber attack against South Korean banks and broadcasters that froze their computer systems for more than a week. North Korea has worked for years to develop the ability to disrupt or destroy computer systems that control public services such as telecommunications and other utilities, according to a North Korean defector familiar with the effort.
