Britains surveillance agency is said to have captured images from millions of Yahoo users webcams as part of a broad program running from 2008 through at least 2012. According to the Guardian, the GCHQ was able to intercept webcam images from more than 1.8 million users over a period of just six months in 2008. Yahoo denies having knowledge of Optic Nerve and calls the alleged program completely unacceptable. The Guardian reports that the NSA assisted in the webcam image collection program, which is known as Optic Nerve.
