[UPDATE] Following the publication of this story, a Sony representative acknowledged Anonymous' breach claim, and refuted it.
"We’ve confirmed that the recent claim that PlayStation Network was illegally hacked and that customer passwords and email addresses were accessed is completely false," reads the statement.
Original story follows below
A since-removed tweet from hacking group Anonymous claimed today that it has breached the PlayStation Network, potentially compromising as many as 10 million accounts. Gamers may not need to be concerned, though, as Sony's business development staffer Shane Bettenhausen tweeted that the claim is "totally fake." However, much like the original Anonymous post, Bettenhausen's tweet has been deleted.
The tweet from Anonymous linked to a Pastebin page, where the author claims to hold a 50GB database with email addresses and passwords. The database gives no indication as to its origin, and appears to be a copy of a list originally posted on March 19.
As of press time, Sony had not responded to GameSpot's request for comment.
