>> North Korea's hackers strike again. South Korean media on Monday reporting that Seoul has thwarted a massive cyber attack. Police investigators discovering more that 140,000 computers at big companies and government offices infected with malicious codes that could be used to launch and even bigger attack. State media say the hack can be traced to Pyongyang, the internet address used by the hackers identical to one from an attack three years ago.
Which froze computer systems at South Korean banks and broadcasters for more than a week. Defectors say Pyongyang has spent years figuring out how to disrupt computer systems that control public services. But North Korea's hackers aren't only focused on the South. In 2014, the US accused Pyongyang of hacking Sony Pictures, leading the studio to cancel the release of The Interview, a comedy, based on the fictional assassination of Kim Jong-un.
North Korea denies the accusation. Seoul has been on heightened alert against cyber attacks after Pyongyang conducted a nuclear test earlier this year.
