Hacker group Lulz Security has claimed that it brought down the public-facing website of the US Central Intelligence Agency.
The alleged hack on CIA.gov occurred on the same day the group opened a telephone request line so its fans could suggest potential targets, the BBC reports.
Lulz Security claimed to have launched denial of service (DoS) attacks on several websites as a result of opening its "request line", although it gave no details.
LulzSec publicized the details of its telephone hotline on its Twitter feed. “Tango down - cia.gov - for the lulz,” the group wrote.
The group said it had used distributed denial-of-service attacks against eight sites suggested by callers.
It also claimed to have hit the websites of gaming magazine The Escapist, and multiplayer games EVE Online and League of Legends.
