Sony executives have issued a statement to Congress in regards to the recent data breaches which compromised personal information of up to 100 million of the company's customers. Sony has now put the blame on the attacks on the group known as Anonymous, who a few weeks ago conducted a large denial of service attack on Sony's servers.
Sony was asked to testify before the House Subcommittee on Commerce, Manufacturing and Trade. Even though Sony declined to attend the meeting the company did issue a letter to committee chairwoman Rep. Mary Bono Mack (R-CA). The letter was summarized on the official Playstation blog site and shown in full on the Playstation Flickr web page.
In short Sony claims they were the victim of a "very carefully planned, very professional, highly sophisticated criminal cyber attack" further explaining that they discovered that the intruders had planted a file on one of the Sony Online Entertainment servers named “Anonymous” with the words “We are Legion.”
In response, Anonymous released a statement Wednesday denying the allegations, but did allow that individual members may have been involved.
"Sony is incompetent," the group said. "While it could be the case that other Anons have acted by themselves AnonOps was not related to this incident and takes no responsibility."
It is still unclear exactly how the attack was orchestrated and whom is responsible. Sony is currently working with several major law enforcement organizations, including the Dept. of Homeland Security and FBI to find the prepetrators.
As we previously reported, Sony believes there is no evidence that credit card info has been lifted from the Playstation Network servers, although it has confirmed that a small number of older credit card numbers from 2007 were taken from an Sony Online Entertainment server.
The entire Sony network remains offline and has not yet brought it back up as the company claims it is taking steps to beef up security.
