This [1] is one of the more telling leaks. It's a technical users guide for NSA employees on using realtime Skype surveillance for all modes including video and landline on arbitrary targets. [1] It even includes debugging guides like why an agent might be getting multiple copies of the same message, as happens when somebody being spied on boots up a new device and all of their messages are sent from Microsoft to them (and the NSA) simultaneously, resulting a copy of older messages (from the snooper's perspective).
