Anonymous, the internet activist group, has denied that it has anything to do with the PlayStation Network hacking and subsequent credit card theft.

Sony had posted its response to the US House of Representatives on the official PlayStation Blog and in it, it stated:

"We discovered that the intruders had planted a file on one of our Sony Online Entertainment servers named 'Anonymous' with the words We are Legion'."

However, in a 900 word statement issued to The Guardian, the group states that it has no business stealing people's credit cards, and any such action would be against the "modus operandi" of the organisation.

This despite Anonymous announcing in April its intent to target Sony websites and executives in response to Sony's lawsuit against George Hotz (PlayStation / iPhone hacker "geohot") and Sony's tracking of IP addresses of visitors to Hotz's blog.

"Anonymous has never been known to have engaged in credit card theft," the statement reads. "Many of our corporate and governmental adversaries, on the other hand. have been known to have lied to the public about Anonymous and about their own activities.

"To the contrary, Anonymous is an ironically transparent movement that allows reporters in to our operating channels to observe us at work and which has been extraordinarily candid with the press when commenting on our own activities, which is why reporters prefer no talk to us for truthful accounts of the situation rather than fallacious public relations departments of our targets."

The PlayStation network is still down - it has been offline now for 15 days.
