New from The Guardian:
Microsoft has collaborated closely with US intelligence services to allow users’ communications to be intercepted, including helping the National Security Agency to circumvent the company’s own encryption, according to top-secret documents obtained by the Guardian.
…The NSA has devoted substantial efforts in the last two years to work with Microsoft to ensure increased access to Skype, which has an estimated 663 million global users.
One document boasts that Prism monitoring of Skype video production has roughly tripled since a new capability was added on 14 July 2012. “The audio portions of these sessions have been processed correctly all along, but without the accompanying video. Now, analysts will have the complete ‘picture’,” it says.
