So I did some reasearch on this Thunder character and from what I found it was a "hacking group" out of Morocco... They call themselves MoroCcaN Inject0r5 Crew/Moroccan Sniper (these could be 2 groups). The character who calls himself thunder's email address is t4h@hotmail.fr. Its odd that they would attack hacker.org. If you do a google search on them youll find many sites that have been hijacked, But they are all for political purposes. A little info on them can be found at the link below. Scroll past the article about the russian cyber malitia.

From what I've read they are a bunch of Script Kiddies that are making a stand for islam.
One of their quote from a hijacked site : "This Hack iS To DeFend Islam That Has Been Harrased by Denmark and USA and Israel"! Stop ! This is not a dream it's a reality"Thanx To Allah For being MuSliMs"
###Sidenote: the member of this site known as "a", is trying to clam resposibility for this. He says it was one of his friends. No garuntee on this though (I highly doubt it)
Quote from the Artcile: Its true, they are in Morocco. We are collecting IP's and locations.With held for opsec reasons.
