The British Surveillance Agency Spied on Millions of Yahoo Video Chats With the NSA's Help

Between 2008 and 2010, Britain's surveillance agency, the GCHQ, worked with the NSA to spy on millions of Yahoo user video chats—even though the people were not suspected of any crime—and store millions of still images from the chats. The Guardian learned this from documents leaked by Edward Snowden.

The project, codenamed "Optic Nerve," ran across a lot of sexually explicit or otherwise graphic imagery in the process of collecting and storing a huge amount of data. The Guardian reports that during a six-month sample of 2008, GCHQ spied on more than 1.8 million Yahoo users around the world. The GCHQ did not ensure that it was avoiding streams involving U.K. and U.S. citizens, and there aren't U.K. laws that prevent agents from looking at this type of data about Americans without a warrant. The GCHQ apparently struggled to make decisions about how to handle and contain the graphic photos collected in Optic Nerve.

A Yahoo spokesperson told the Guardian that the company had absolutely no prior knowledge of the surveillance.

We were not aware of, nor would we condone, this reported activity. 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. ... We are committed to preserving our users' trust and security and continue our efforts to expand encryption across all of our services.

Other documents have revealed GCHQ spying tactics that involve chat rooms and chat services, and project Optic Nerve is slightly less surprising in light of these other known actions. But that doesn't make it anything less than shocking. If they're going after a suspect, that's one thing, but why would GCHQ agents even want to know what average people are doing on video chat. You don't need to fill endless servers to know that it's gonna alternate between blurry faces, cats, and genitalia.
