British Spies Said To Intercept Yahoo Webcam Images

A British intelligence agency collected video webcam images — many of them sexually explicit — from millions of Yahoo users, regardless of whether they were suspected of illegal activity, according to accounts of documents leaked by Edward J. Snowden.

The surveillance effort operated by Britain’s Government Communications Headquarters, or GCHQ, was code-named Optic Nerve. Images from Yahoo webcam chats were captured in bulk through the agency’s fiber-optic cable taps and saved to a GCHQ database.

It is unclear how much of the data was shared with American officials at the National Security Agency, though the British ran queries of the data using a search tool provided by the N.S.A. called XKeyscore, according to a report on Thursday by The Guardian.

The report did not indicate whether the agency also collected webcam images from similar services, such as Google Hangouts or Microsoft’s Skype. The Guardian did say the British intelligence agency was studying the possibilities of using the cameras in Microsoft’s Kinect devices, which are used with its Xbox game consoles, to spy on users.
