The Government’s Secret Wiki for Intelligence

Analysts reportedly tucked classified information about Russian hacking inside Intellipedia for safekeeping.

During the final weeks of the Obama administration, officials began to worry that the results of ongoing investigations into Russia’s election-related hacking might get swept under the rug once President Trump took office. They decided to leave a trail of breadcrumbs for congressional investigators to find later, according to a report from The New York Times.

In another age, the paper trail may have taken the form of notes stuffed into a box in a forgotten archive. But this being the 21st century, some of the breadcrumbs were submitted to an online wiki. According to the Times, intelligence officers in various agencies rushed to complete analyses of intelligence about Russian hacking and file the results, at low classification levels, in a secret Wikipedia-like site for intelligence analysts. There, the information would be widely accessible among the intelligence community.

That site, called Intellipedia, has been around for more than a decade. It’s made up of three different wikis, at different classification levels: one wiki for sensitive but unclassified information, another for secret information, and a third for top secret information. Each wiki can only be accessed by employees in the U.S. intelligence community’s 17 agencies who have the appropriate clearance level.

Intellipedia was formally launched in 2006, but grew slowly at first. “It was received skeptically by most,” said Carmen Medina, the former CIA director for the study of intelligence and one of the first officials to green-light the project. “Analysts were not really rewarded for contributing to Intellipedia.”

Since then, the wikis have grown steadily. According to a release celebrating the site’s second anniversary, the system housed nearly 50,000 articles by March 2008. In January 2014, the National Security Agency responded to a Freedom of Information Act request with the latest statistics: The three domains had just over 269,000 articles, more than 40 percent of which were found on the top secret wiki. (It’s not clear whether articles are duplicated across the wikis.)

Built on the same software platform as Wikipedia, Intellipedia's articles are often cribbed directly from the free encyclopedia, but with sensitive classified information added by analysts. “About everything that happens of significance, there’s an Intellipedia page on,” Sean Dennehy, one of the site’s founders, told The Washington Post in 2009. An article about the terrorist attack in Mumbai was filled with sensitive information before it was reported in the popular press, Dennehy said.

In 2009, Dennehy and Don Burke, both CIA analysts, won a Service to America Medal for their work on Intellipedia.

Their site is meant to help analysts collaborate across agencies: Improving cross-agency communication was one of the main recommendations set forth by the 9/11 Commission, which led to the establishment of the Office of the Director of National Intelligence in 2005. That’s the agency that now has custody of Intellipedia.
