Hacker group "Anonymous" have denied involvement in the breach in a blog post titled "For Once We Didn't Do it" however it admitted rogue hackers could be responsible.
There is no representative for anonymous. That statement is false. I wouldnt wait too long to hang onto your credit card details either. A program is probably being developed to take everyones details and money at one time, rather than risk doing as many as possible before people start cancelling their cards. As long as noones money is being stolen now, most people will be under the impression that noone has gained access to it. dont be fools, protect yourself. People who are able to hack into such organisations are not to be taken lightly, you're a fool to think you are safe. cancel your cards now.
