North Korea’s Reconnaissance General Bureau cyberwarfare unit has increased in size for 500 personnel to as many as 3,000, defector says.

Many countries around the world are actively bolstering their cryberwar teams, including the UK, according to defector Kim Heung-kwang, who left the bizarre Communist state in 2003. The country’s unstable behaviour is being watched closely, including an incident in which it shelled a South Korean fishing village last November.”]
