A letter purporting to represent the Anonymous hacking group claims the organization was not behind the PlayStation Network attack.
"If a legitimate and honest investigation...is conducted, Anonymous will not be found liable," reads the letter, which was posted to the Web yesterday. "While we are a distributed and decentralized group, our 'leadership' does not condone credit card theft."
The letter is a response to accusations on Sony's part that Anonymous is responsible for last month's massive assault on its customer data.
"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 named 'Anonymous' on one of those servers, a file containing the statement with the words 'We are Legion,'" Sony Computer Entertainment Chief Kazuo Hirai wrote in a letter to Congress.
Last month, Sony announced that the personal information of its 77 million PlayStation Network and Qriocity users was stolen in what it's now calling a "very carefully planned, very professional, highly sophisticated criminal cyberattack designed to steal personal and credit card information for illegal purposes."
