It is believed a series of Anonymous attacks called Operation Killing Bay started around 2013 in protest against Japan’s whale hunting and the annual dolphin hunts in Taiji, Wakayama Prefecture, in September.Last year, to protest against the dolphin hunting in Taiji, distributed denial of service (DDoS) attacks were launched against government offices websites and infrastructure operators such as airports. DDoS attacks are aimed at rendering websites and other online services unavailable by sending a huge amount of data to the server.
According to police, the number of cyber-attacks Anonymous is believed to be involved in has grown since September. There were no cyber-attack-related website problems from May to August, but 29 incidents were confirmed in September, followed by 26 in October. From Nov. 1 to Nov. 27, there were 53 cases, bringing the total from September to Nov. 27 to 108.
