'A whole new level of violation of our users' privacy'

Material included large quantity of sexually explicit images

Britain's surveillance agency GCHQ, with aid from the US National Security Agency, intercepted and stored the webcam images of millions of internet users not suspected of wrongdoing, secret documents reveal.

In one six-month period in 2008 alone, the agency collected webcam imagery – including substantial quantities of sexually explicit communications – from more than 1.8 million Yahoo user accounts globally.

Yahoo reacted furiously to the webcam interception when approached by the Guardian. The company denied any prior knowledge of the program, accusing the agencies of "a whole new level of violation of our users' privacy".

...Optic Nerve, the documents provided by NSA whistleblower Edward Snowden show, began as a prototype in 2008 and was still active in 2012, according to an internal GCHQ wiki page accessed that year.

The system, eerily reminiscent of the telescreens evoked in George Orwell's 1984, was used for experiments in automated facial recognition, to monitor GCHQ's existing targets, and to discover new targets of interest. Such searches could be used to try to find terror suspects or criminals making use of multiple, anonymous user IDs.

...It is not fully clear from the documents how much access the NSA has to the Yahoo webcam trove itself, though all of the policy documents were available to NSA analysts through their routine information-sharing. A previously revealed NSA metadata repository, codenamed Marina, has what the documents describe as a protocol class for webcam information.

In its statement to the Guardian, Yahoo strongly condemned the Optic Nerve program, and said it had no awareness of or involvement with the GCHQ collection.

"We were not aware of, nor would we condone, this reported activity," said a spokeswoman. "This report, if true, represents a whole new level of violation of our users' privacy that is completely unacceptable, and we strongly call on the world's governments to reform surveillance law consistent with the principles we outlined in December.

"We are committed to preserving our users' trust and security and continue our efforts to expand encryption across all of our services."

If you got full-frontal during a webcam chat on Yahoo Messenger in the latter part of the last decade (we hope you didn’t… then or ever), there’s a possibility that spies at the British GCHQ spy agency as well as some at the U.S. National Security Agency got a look at your junk.
