These collection resources are extensive [see attached NSA slides 1, 2, 3, 4, 5]; they include hundreds of trace route programs that trace the path of packets going across the network and tens of thousands of hardware and software implants in switches and servers that manage the network. Any emails being extracted from one server going to another would be, at least in part, recognizable and traceable by all these resources.
The bottom line is that the NSA would know where and how any “hacked” emails from the DNC, HRC or any other servers were routed through the network. This process can sometimes require a closer look into the routing to sort out intermediate clients, but in the end sender and recipient can be traced across the network.
The various ways in which usually anonymous spokespeople for U.S. intelligence agencies are equivocating – saying things like “our best guess” or “our opinion” or “our estimate” etc. – shows that the emails alleged to have been “hacked” cannot be traced across the network. Given NSA’s extensive trace capability, we conclude that DNC and HRC servers alleged to have been hacked were, in fact, not hacked.
The evidence that should be there is absent; otherwise, it would surely be brought forward, since this could be done without any danger to sources and methods. Thus, we conclude that the emails were leaked by an insider – as was the case with Edward Snowden and Chelsea Manning. Such an insider could be anyone in a government department or agency with access to NSA databases, or perhaps someone within the DNC.
