There are numerous groups that may have leaked this. For instance, it could very well be that the NSA itself put this material out there. Consider the following. Perhaps the NSA has the exact capabilities that many people are now complaining against, specifically the direct access stuff. They "leak" a document about this as most people suspect they do anyways. The media publishes these documents. People get worried. New technologies bubble to the surface in response to this. The NSA observes those new technologies. Now, they didn't have to hunt down the tools used to hide data from them. They've cleverly "forced" those tools out into the open. It's a lot easier to spy on people when you know what tools are being used to keep you from spying on people.
