Notorious Internet hacker group "Anonymous" has taken responsibility for an attack against the official Central Intelligence Agency (CIA) website today. The CIA website, as of writing, is unresponsive and leads to an error message when trying to load it. "CIA TANGO DOWN," the hacker group tweeted via their @YourAnonNews Twitter account Friday afternoon. 

Over the past few weeks, Anonymous has been making news quite a bit, first by taking down the Federal Bureau of Investigation's (FBI) website, and then the Boston Police Department website last week. These recent attacks come as retaliation following popular file hosting website Megaupload being shut down by the U.S. government because of piracy concerns.
