Account information, including passwords and credit card numbers, were released Friday for web services like Amazon.com, Xbox Live, PlayStation Network and Hulu Plus. The list was posted by a group that claims to be associated with the hacking activists called "Anonymous." Reuters

A group of self-described hackers released thousands of passwords and credit card numbers from online services like Amazon, Hulu Plus, Xbox Live and the PlayStation Network on Friday. The group claimed to be aligned with the loosely knit group of “hacktivists” called “Anonymous.”

The information was released in a document posted on text storage service Ghostbin. It was inactive early on Saturday morning. The list included over 10,000 entries, including retailers like Walmart and Dell, video game services like EA Games, Origin.com and Twitch.TV, as well as login information for a number of subscription pornography sites like Brazzers.com. Credentials for online services for VPNCyberGhost and UFC TV were also listed.

Update: CyberGhost has responded with a statement: "The group just published a list of [promotional] activation keys for our service. Anybody could do that, because we give these keys away for free. The keys are all blocked... [so] this is not a loss for us and [not a] security vulnerability for our users."

Update 2: The Twitter account claimed on Monday, Dec. 29 that it had "reposted" account details it leaked over the past two years, following up on criticism that the leak was fake. The disclosure means that most, if not all, of the accounts listed have had their credentials changed since they were originally leaked. The original Ghostbin post has also been removed.

The information also included expiration dates, security codes, phone numbers and names for some of the accounts. Amazon, Microsoft, Hulu Plus and Sony did not respond to a request for comment, and the International Business Times could not immediately verify the claims.

Xbox Live and PlayStation Network (PSN) were taken down by a denial of service attack launched by the hacking group “Lizard Squad” on Christmas. Microsoft was able to restore access on Friday after Megaupload founder Kim Dotcom offered the group free access to the data storage service, but PlayStation owners were still unable to sign on after midnight on Saturday morning.
