North Korea hacking U.S. and South Korea

North Korean citizens have extremely limited access to the Internet, unlike South Korea which has one of the world's highest per capita rates of broadband Internet connection.

However their government, under the thumb of dictator Kim Jong Il, is not shy about using technology to further its aims. JoongAng Daily cites shadowy "intelligence sources in Seoul" when it reports North Korea has set up a cyber warfare unit with the aim of disrupting US and South Korean networks. The source also claims North Korea visits US military sites more frequently than any other country.

The North's military has expanded their cyber warfare unit, staffing it with about 100 personnel, mostly graduates of a Pyongyang university that teaches computer skills, Yonhap news agency reported.
