Today on bungie.net an unknown hacker calling itself AdjutantReflex opened a thread titled System Integrity Confirmed (link at the bottom). later, on the HBO forums a topic with the same name was created by, you guessed it, AdjutantReflex.
Go to http://carnage.bungie.org/haloforum/halo.forum.pl?read=808840 for the HBO posts.
At this point you can only speculate what will come of this. Is this I love bees all over again?
