CIA website hacked in attack 'claimed' by shadowy cyber group Anonymous A message posted on Friday on a Twitter page and on Tumblr feed affiliated with Anonymous celebrated the blocking of the site. "CIA Tango Down" read the posting, using US special forces terminology for killing an enemy. Jennifer Youngblood, a CIA spokeswoman, said on Friday night: "We are aware of the problems accessing our website, and are working to resolve them." Anonymous claimed responsibility for shutting down the homepages of the Department of Justice and FBI last month in retaliation for the US government closing the controversial Megaupload filesharing websites. Alabama state and Mexican mining company websites were also hacked on Friday. Web pages linked to Anonymous claimed responsibility for both attacks. Earlier this month, a conference call between Scotland Yard and the FBI on tacking computer hacking was intercepted and published by a member of the Anonymous group.
