CIA web-site was attacked by the hackers' group Lulz Security last night. The site was unavailable for several hours, but then the situation normalized. The agency didn't leave any comments upon was it really a hackers' attack. Also, the Agency didn't comment upon the consequences of the attack.
On Monday, Lulz Security claimed about the attack on the USA Senate web-site and about stealing of a couple of documents from the server. But as the sergeant-at-arms said later to the journalists, the hackers only got access to the base of documents, which is free-accessed. They failed to tamper the Senate's bases.
