Jacob Appelbaum, Laura Poitras and others have another NSA aticle with an enormous Snowden document dump on Der Spiegel, giving details on a variety of offensive NSA cyberoperations to infiltrate and exploit networks around the world. There's a lot here: 199 pages. (Here it is in one compressed archive.)
Paired with the 666 pages released in conjunction with the December 28th Spiegel article (compressed archive here) on the NSA cryptanalytic capabilities, we've seen a huge amount of Snowden documents in the past few weeks. And, at least according to one tally, 3560 pages in all.
