This story is a few days old but I thought it was worth giving an airing.
According to an un-named South Korean intelligence official, North Korea has been operating a cyber warfare unit that seeks to hack into South Korea's military command communication network and destroy Internet servers.
The same official said the North set up a cyber warfare unit (named "unit 121") about eight years ago with around 1,000 personnelHe said the unit had hacked into the South Korean and U.S. Defense Department and has caused much damage in the South.
How dare they! You wouldn't catch us good guys doing anything so sneaky.
