Skype now has a backdoor that permits government surveillance of users’ video and audio calls, according to a new report in the Guardian.

The report, based on leaked slides from the National Security Agency, appears to confirm growing suspicions about the popular video chat service — and indicates calls may be monitored as easily as an old-fashioned phone call.

One document quoted by the newspaper says intelligence analysts began to be able to monitor Skype video calls in 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.’”
