North Korea behind March cyberattack, says South Korea | Security & Privacy - CNET News: "South Korea has accused North Korea of launching a recent cyberattack that hit tens of thousands of PCs. A spokesman for South Korea's Internet agency said today that six computers in North Korea were identified as the source of the attack, according to The Guardian. Those computers used more than 1,000 IP addresses from across the world to infect 48,000 PCs and servers at South Korean banks and broadcasting stations. The spokesman told the Associated Press that the attack mimicked past hacking attempts by North Korea and pointed the finger at an espionage agency run by the military. The attack also seemed to have been in the planning stage for around eight months. 'We saw evidence that the attack was extremely carefully prepared,' the spokesman said at a news briefing today."
