Japanese police say the international hacking group Anonymous has attacked at least 97 websites in Japan since September.
The National Police Agency says cyber attacks by Anonymous have intensified since September. The group has made online sites of companies and other institutions inaccessible by inundating them with huge volumes of traffic. This tactic is called DDos, or distributed denial of service. As of Thursday, Anonymous had claimed responsibility on Twitter for at least 97 cyber attacks.
The hackers have targeted a variety of websites including those for aquariums, groups related to dolphin and whale hunting, airports, news organizations and government offices.
The police have been collecting information to identify where the attacks were launched. They are using more equipment to analyze communications logs.
Police warn that cyber attacks may increase as the group seeks attention in the run-up to next year’s Ise-Shima Summit of major nations in Mie Prefecture, western Japan. Police urge website administers to set up backup sites and take other protective measures.
