CIA's "vengeful librarians" monitor Twitter and Facebook

The Central Intelligence Agency (CIA) has established a compound in Virginia that focuses on one very important aspect of international espionage: social network spying.

McLEAN, Va. (AP) — In an anonymous industrial park in Virginia, in an unassuming brick building, the CIA is following tweets — up to 5 million a day.

At the agency's Open Source Center, a team known affectionately as the "vengeful librarians" also pores over Facebook, newspapers, TV news channels, local radio stations, Internet chat rooms — anything overseas that anyone can access and contribute to openly.

From Arabic to Mandarin Chinese, from an angry tweet to a thoughtful blog, the analysts gather the information, often in native tongue. They cross-reference it with the local newspaper or a clandestinely intercepted phone conversation. From there, they build a picture sought by the highest levels at the White House, giving a real-time peek, for example, at the mood of a region after the Navy SEAL raid that killed Osama bin Laden or perhaps a prediction of which Mideast nation seems ripe for revolt.

Yes, they saw the uprising in Egypt coming; they just didn't know exactly when revolution might hit, said the center's director, Doug Naquin.

The center already had "predicted that social media in places like Egypt could be a game-changer and a threat to the regime," he said in a recent interview with The Associated Press at the center. CIA officials said it was the first such visit by a reporter the agency has ever granted.

The CIA facility was set up in response to a recommendation by the 9/11 Commission, with its first priority to focus on counterterrorism and counterproliferation. But its several hundred analysts — the actual number is classified — track a broad range, from Chinese Internet access to the mood on the street in Pakistan.

While most are based in Virginia, the analysts also are scattered throughout U.S. embassies worldwide to get a step closer to the pulse of their subjects.

The most successful analysts, Naquin said, are something like the heroine of the crime novel "The Girl With the Dragon Tattoo," a quirky, irreverent computer hacker who "knows how to find stuff other people don't know exists."

Those with a masters' degree in library science and multiple languages, especially those who grew up speaking another language, "make a powerful open source officer," Naquin said. Read More
