Sony sets crosshairs on Anonymous
Company says system was breached during denial of service attacks by the hacker group
Sony Online Entertainment has revealed in its latest blog post that it discovered a file on its servers named ‘Anonymous' with the words ‘We are Legion', adding fuel to the rumours that Anonymous perpetrated the Sony PlayStation network, Qriocity and Sony Online Entertainment hacks.
Sony has now been asked to testify in front of the US Congress House Subcommittee on Commerce, Manufacturing and Trade on the subject of ‘The Threat of Data Theft to American Consumers', so that the company can answer questions about its recent PlayStation Network security breach.
Sony declined the invitation to attend and instead sent a letter to the committee chairwoman Rep Mary Bono Mack (R-CA).
Sony has said in the letter that the hack happened at the same time it was dealing with major denial of service attacks perpetrated by Anonymous and the Anonymous attack may have aided hackers to breach its systems.
"This cyber-attack came shortly after Sony Computer Entertainment America was the subject of denial of service attacks launched against several Sony companies and threats made against both Sony and its executives in retaliation for enforcing intellectual property rights in US Federal Court," read the letter.
On page two Sony reiterated this information.
"When Sony Online Entertainment discovered this past Sunday afternoon that data from its servers had been stolen, it also discovered that the intruders had planted a file on one of the servers named ‘Anonymous' with the words ‘We are Legion'. Just weeks before several Sony companies had been the target of a large-scale, co-ordinated denial of service attack by a group called Anonymous... Almost two weeks ago one or more criminals gained access to PlayStation Network servers at or around the same time these servers were experiencing denial of service attacks," said the letter.
Sony goes on to reveal that one of the reasons that the Sony security team may have missed the hack was that they were concentrating on stopping the denial of service attack. Sony says that this diversion may have been intentional to allow the hackers to enter the Sony systems and steal user information.
"Whether those who participated in the denial of service attacks were conspirators or whether they were simply duped into providing cover for a very clever thief we may never know," Sony stated in the letter.
Anonymous have repeatedly denied being behind the massive Sony hack that saw over 100 million users' personal data being stolen by the cyber-criminals that breached Sony network security.
