On Friday, WikiLeaks published three summaries of NSA intercepts of German government communications. To me, the most interesting thing is not the intercept analyses, but this spreadsheet of intelligence targets. Here we learn the specific telephone numbers being targeted, who owns those phone numbers, the office within the NSA that processes the raw communications received, why the target is being spied on (in this case, all are designated as "Germany: Political Affairs"), and when we started spying using this particular justification. It's one of the few glimpses we have into the bureaucracy of surveillance.
Presumably this is from the same leaker who gave WikiLeaks the French intercepts they published a week ago. (And you can read the intelligence target spreadsheet for France, too. And another for Brazil that WikiLeaks published on Saturday; Intercept commentary here.) Now that we've seen a few top secret summaries of eavesdropping on German, French, and Brazilian communications, and given what I know of Julian Assange's tactics, my guess is that there is a lot more where this came from.
Der Spiegel is all over this story.
