This thread is/was hilarious, as one of the people who's name was put on the deface I think I may be able to enlighten this thread some... if anyone cares at this point.
Firstly the main person behind the people deface is ev0 aka xyz, ev0 never even found the exploit. He is just a drug junky with no talents other than sucking up to his greaters on the internet in a pursuit for e-fame. He is sour not over anything to do with "anonymous" but because my good friend chippy1337 has demolished him many times by rooting his servers, compromising his email accounts etc. chippy1337 likes to "troll" (just look at his handle) and has many haters...
The whole idea was very stupid move on behalf of ev0 since it lead to his arrest...LOL
As to why "anonymous" is/was being mentioned in this whole thing it is because of the mention of a former anonops admin on the deface and the fact that the media for some reason likes to implicate "anonymous" in things related to netsec.
Also regarding anonymous... People have A LOT of misconceptions about anonymous, the general idea is that it is leaderless, de-centralized is legion etc. In the broader sense when you look at it as a movement from 2006 to present this mostly holds true. That said the current operations such as operation payback etc are far from leaderless and de-centralized, anything that has come out of anonymous in the past year has come out of "anonops".
Anonops is full of leaders... most of these leaders are kids who are slowly being corrupted with the power they hold and the ego trip it is giving them. Anonops is like a propaganda machine that pushes the idea that anonymous is de-centralized, leaderless etc..
That's all I am going to say since I don't want to blog about anonymous, I wish more people would just lurk the irc channels etc more and realize for themselves exactly how it is run... one could easily build ranks in anonymous/anonops and see the leader structure first hand.
tl;dr the person behind it has been arrested and anonymous had nothing to do with it, also chippy1337 is boss.
