Japanese government websites came under cyberattack over the Weekend - 20th Sept 2011

The websites of some Japanese government agencies came under cyberattack the past weekend, and access to them was temporarily interrupted, the National Police Agency said Monday.

The attacks were carried out from Saturday to Sunday, and affected the websites of the National Personnel Authority, a video distribution service and a website operated by the Cabinet Office, the NPA said.

The NPA said it belieLinkves the affected websites came under so-called distributed denial-of-service (DDoS) attacks in which hackers send a massive amount of data to a target website, overwhelming its ability to respond or function promptly.

According to the NPA, online messages were posted in China calling for attacks on Japanese websites ahead of Sunday, the 80th anniversary of an event which triggered the Manchurian Incident in 1931 that led to Japan's invasion of China.

Japanese government agencies also faced cyberattacks in September last year and in July this year, and the NPA said about 90 percent of the attacks were carried out by Chinese IP addresses. Source
