SKorea: NKorea behind cyberattack on Seoul daily

Last year's cyberattack came only days after North Korea's military warned that its troops had aimed artillery at the specific coordinates of the JoongAng Ilbo and other media groups over perceived insults on children's festivals in Pyongyang.

Animosity has run high between the Koreas since two attacks blamed on Pyongyang killed 50 South Koreans in 2010. Last month, North Korea successfully shot a satellite into space on a long-range rocket, a launch South Korea and the U.S. condemned as a banned test of missile technology.

The Korean Peninsula is still technically at war because the 1950-53 Korean War ended with an armistice, not a peace treaty.
