A NUMBER OF JAPANESE WEBSITES, including those belonging to banks and other institutions are under cyber attack.
The Japanese National Police Agency says that at least 19 websites are under attack, and have been since the country nationalised the Senkaku Islands, according to a report at the Japan Times.
The attacks seem to be coming from China, according to an NPA official, and were at a peak on Sunday.
The attackers are targeting a range of websites, including banks and universities, and it appears that they are being coordinated through Chinese hacking websites and bulletin boards.
Messages there criticise Japan with messages like, "Don't invade Diaoyu," says the report.
According to a translation of the NPA's alert (PDF) that we have seen, as many as 300 Japanese websites could be targeted in the attacks, and around 4,000 people are thought to be involved.
Denial of service is the chosen manner of attack, and if control of websites is taken their contents are replaced with Chinese text and a picture of the Senkaku Islands. µ
