Individuals claiming to be a part of the hacktivist group Anonymous have claimed responsibility for a series of cyber attacks on Japanese government websites. The websites for Japan's Finance Ministry, Supreme Court, and the DPJ and LDP political parties were taken down temporarily by attacks. The sites are now back online.
The Twitter account @op_japan – which is supposedly associated with Anonymous – claimed responsibility. The Twitter account said that the attacks were in response to Japan's new anti-piracy bill. The new law adds jail time to existing law and expands what is illegal to use like copyright circumvention hardware (R4 devices, for example).
The new law would "result in scores of unnecessary prison sentences to numerous innocent citizens", the Anonymous feed said.
Ministry official Takanari Horino told the BBC that a number of the Finance Ministry's web pages had been defaced on Tuesday and an unauthorized link was posted on the site.
"We are aware of the Anonymous statement referring to the new copyright law, but we don't know at this point if the cyber-attacks are linked to the group," he added.
