Using its Twitter feed, LulzSec took credit for the outage of the CIA.gov website during the early evening hours. The CIA says it is investigating the brief outage.
LulzSec announced the attack just before 6 p.m. EDT with the phrase "Tango down," and pointing to www.cia.gov. The CIA's website does not include classified data and has no impact on the CIA's operations, according to officials.
In recent weeks, LulzSec has attacked multiple gaming websites, an FBI website, the U.K.'s National Health Service, a porn site, and a Senate website. On Tuesday, LulzSec published the login and passwords for nearly 26,000 users of a porn site.
The group seems gleeful in its tweets. "Lulz Security, where the entertainment is always at your expense, whether you realize it or not," the group tweeted on Wednesday. "Wrecking your infrastructures since 2011."
