I'm pretty interested the tools the whistleblower employs to avoid detection. They are alluded to in the end of Citizenfour, but I'm not sure they are specifically named. I assume they are using SecureDrop, and the continuing survival of the source attests to the strength of it's security. The amount of NSA scrutiny laser-focused on Jeremy Scahill must be insane. He probably has an entire team dedicated to monitoring everything he does, since they are trying to find the leak. I can't think of a better battle test of a security technology than whatever he and the source are using to communicate, since they basically screamed about their partnership in Citizenfour.
