N. Korea Has Army of 6K Hackers: S. Korea

South Korea says rival North Korea has a 6,000-member cyberarmy dedicated to disrupting the South's military and government. The figure is a dramatic increase from South Korea's earlier estimate that the North had a cyberwarfare staff of 3,000. Seoul's Defense Ministry also says in a report that North Korea may now have the ability to strike the US mainland because of its recent progress in missile technology and is advancing in efforts to miniaturize nuclear warheads to mount on such missiles. The United States stands pretty convinced that the North's cyberwarriors are behind the Sony hack.
