Flickr | WikiLeaks has published more than 8,000 documents purportedly taken from the CIA, March 7, 2017.

WikiLeaks has published thousands of documents that it says come from the CIA's Center for Cyber Intelligence, a dramatic release that appears to give an eye-opening look at the intimate details of the agency's cyberespionage effort.

The dump of more than 8,000 documents could not immediately be authenticated by The Associated Press and the CIA declined comment, but WikiLeaks has a long track record of releasing top secret government documents. Experts who've started to sift through the material said it appeared legitimate - and that the release was almost certain to shake the CIA.

"There's no question that there's a fire drill going on right now," said Jake Williams, a security expert with Augusta, Georgia-based Rendition Infosec. "It wouldn't surprise me that there are people changing careers - and ending careers - as we speak."

Bob Ayers, a retired U.S. intelligence official currently working as a security analyst, agreed, saying that the release was "real bad" for the agency.

Another catastrophic breach

If the authenticity of the dump were officially confirmed, it would represent yet another catastrophic breach for the U.S. intelligence community at the hands of WikiLeaks and its allies, which have repeatedly humbled Washington with the mass release of classified material, including hundreds of thousands of documents from the State Department and the Pentagon.

WikiLeaks, which had been dropping cryptic hints about the release for a month, said in a lengthy statement that the CIA had "recently" lost control of a massive arsenal of CIA hacking tools as well as associated documentation. The radical transparency organization said that "the archive appears to have been circulated among former U.S. government hackers and contractors in an unauthorized manner" and that one of them "provided WikiLeaks with portions of the archive."

Jonathan Liu, a spokesman for the CIA, said: "We do not comment on the authenticity or content of purported intelligence documents."

Williams, who has experience dealing with government hackers, said that the voluminous files' extensive references to operation security meant they were almost certainly government-backed.

Improvised surveillance devices

"I can't fathom anyone fabricated that amount of operational security concern," he said. "It rings true to me."

"The only people who are having that conversation are people who are engaging in nation-state-level hacking," he said.

The documents cover a range of topics, including what appeared to be a discussion about how to compromise smart televisions and turn them into improvised surveillance devices.

WikiLeaks said the leaked data also included details on the agency's efforts to subvert American software products and smartphones, including Apple's iPhone, Google's Android and Microsoft's Windows.

A "substantial library" of digital espionage techniques borrowed from Russia and other countries is in the data as well, WikiLeaks said.

Ayers noted that WikiLeaks has promised to release more CIA documents, saying Tuesday's publication was just "the first full part of the series."

"The damage right now is relatively high-level," he said. "(But) the potential for really detailed damage will come in the following releases."
