Lulz Security or LulzSec, the hackers collective, claimed responsibility for disabling the U.S. Central Intelligence Agency's (CIA) public website on Wednesday, two days after hacking the U.S. Senate's computer system.

“Tango down — cia.gov — for the lulz,” the group tweeted from its Twitter account, @LulzSec.

Just after Lulz sent the message for a while, the CIA’s webpage was slow to load in multiple attempts on multiple browsers on Wednesday evening.

The users had difficulty in accessing the agency's website. However, there was neither any impact on the CIA's operation nor any classified data was stolen.
On Monday, LulzSec hacked a Senate server but did not breach other files, according to a Capitol Hill law enforcement official. The hackers said they hacked just for kicks to help the government fix their (cyber security) issues.

 “We are looking into these reports,” CIA spokesperson Jennifer Youngblood said.

Lulz recently attacked some high-profiled companies and organizations such as Sony, Bethesda Softworks, the U.S. Senate and the Public Broadcasting Service (PBS).

The group said recently it will take revenge after dozens of Anonymous hackers were arrested in Spain.

LulzSec has also set up a hotline for suggestions on targets, tweeting the number on Wednesday. Now accepting calls from true lulz fans - let's all laugh together at butthurt gamers. 614-LULZSEC, accepting as many as we can, let's roll, the group said.

The response was overwhelming in hours. The group claimed to have missed 5,000 calls and received 2,500 voicemails. The 614 area code represents the metropolitan area of Columbus, Ohio, but authorities could not locate members of LulzSec simply by the area code.
