I know that much. Anonymous more or less has nothing to do with the attack on SOE, but they are responsible for the PSN takeover. Whoever took the credit card info, whether they lay claim to being part of anon or not, was just making good use of the chaos.
I don't think that is the case here... there is no doubt that 4chan is the Wretched Hive of the Internet. It's been a known fact for years now, how moot still manages to get hosting for the site is something of a miracle. They are good but "Anonymous" is NOT this kind of organized... attacks of this nature require some manner of thought, it's quite possible that this intrusion is years in the making given what happened and all the facts that Sony has made known.
Plus add in patterns that "Anonymous" is known for, calling out Anon for something like this seems odd to me. Sony is looking for someone or some persons, this person(s) remains anonymous... but to claim that "Anonymous" is the one that attacked PSN is far fetched, this is a level of chaos and panic is not something that you can do in a few weeks. Granted, Anonymous is far from innocent but to be honest this is something that I don't think that they are capable of. And given the information that was taken, it's something that I don't think that Anon really cares to have...
That said, I would not doubt it if the attacker(s) are users of the site.... Wretched Hive that it is, but if that it what is takes to be among the hackers known as "Anonymous", god help us all.
