Hacker group LulzSec, as promised, posted information it took from Sony Entertainment and Sony BMG.

The information, which includes about a million usernames and passwords of customers in the U.S., Netherlands and Belgium, is available for download and posted on the group’s site.

In a statement, Jim Kennedy, executive vice president of Global Communications for Sony Pictures Entertainment, said,  “We are looking into these claims.”

A release posted on LulzSec’s page said that the group has more information, but that it can’t afford to fully copy all of the information it stole. The group also said that none of the information it took from Sony was encrypted.

“Our goal here is not to come across as master hackers, hence what we're about to reveal: SonyPictures.com was owned by a very simple SQL injection, one of the most primitive and common vulnerabilities, as we should all know by now,” the group wrote. “From a single injection, we accessed EVERYTHING. Why do you put such faith in a company that allows itself to become open to these simple attacks?”

LulzSec is not believed to be involved in the Sony breaches that resulted in 77 million user accounts being compromised in April, and the group has denied that it has ever attacked the PlayStation Network.
