Around 3pm PST on Wednesday, the hacker group Lolz Security group claimed on their twitter feed that they had taken down the public facing CIA website. 

This attack follows LulzsSec's attack on the online hacker forum 4chan earlier in the day, enraging members of the hacker group Anonymous.    

With members of the hacker group Anonymous currently searching out the identities of the Lulz attackers, the group may now be having the same people that found Osama Bin Laden looking for them.
