Sony Accuses Anonymous in One of Largest Breaches Ever

In a letter to Congress released yesterday, a Sony Corp. executive said the company found a mocking message left during a recent cyber attack, but still does not know who stole personal information from more than 100 million of the company’s online-gaming accounts.

Although the intruders deleted all traces of the hack, Sony said it uncovered a file left on its servers titled “Anonymous.” The contents of that file said “We are Legion,” which is the slogan of hacktivist collective Anonymous.

“Just weeks before, several Sony companies had been the target of a large-scale, coordinated denial of service attack by the group called Anonymous,” Sony Computer Entertainment chief Kazou Hirai wrote in the letter to Congress.

Anonymous last month retaliated after Sony sued two individuals who were distributing instructions on how to hack a PlayStation 3 game system. Addressing Sony in a public letter on the Anonymous website, a representative wrote the company had “abused the judicial system in an attempt to censor information on how your products work.”

“In doing so, you have violated the privacy of thousands of innocent people who only sought the free distribution of information,” the Anonymous member said.

Despite Anonymous’ previous gripe with Sony, Barrett Brown, a liberal writer who is affiliated with Anonymous, said there was no evidence the group had engaged in credit-card theft.

“There is no reason to believe anyone involved in Anonymous did that,” he told The Wall Street Journal.

Additionally, a release on the AnonOps website states the collective did not partake in the attacks against Sony, and “does not take responsibility for what has happened.”

“A more likely explanation is that Sony is taking advantage of Anonymous’ previous ill will towards the company to distract users from the fact that the outage is actually an internal problem with the company’s servers,” the April 24 release said.
