KUALA LUMPUR -- Malaysia has beefed up security on all fronts including cyberspace after diplomatic relations with North Korea deteriorated in the aftermath of the assassination last month of Kim Jong Nam, the estranged half-brother of leader Kim Jong Un.
In the past, North Korea has been suspected of hacking websites in Japan and South Korea. South Korean authorities believe hackers from the North were behind attacks last August on computer servers linked to the military, according to Yonhap news agency in December.
