121 possible that Snowden smuggled in a key logger in his backpack, it could not be operated wirelessly inside the Center because, like all other NSA facilities, the computers had been insulated to lock-out wireless transmission. This precaution was taken to guard against an EMP, or Electro-Magnetic Pulse, attack by an enemy. If so, the only way Snowden could intercept key strokes was to attach a cable from his key logger to each of his fellow workers’ computers. In this scenario, he would have to surreptitiously build his own wired network connecting his hidden key logger to 24 separated computers. Moreover, he would have to do this wiring in an open-plan office where he could not count on these additional wires, even if rigged one by one, not being noticed by either other analysts on the room or the geek squad of system administrators who regularly checked connections. Making the task even more risky, according to my Booz Allen source, there were closed-circuit cameras. The only way he could mitigate the risk of detection was by having someone help him build this network. There was a further security barrier he had to get by. Even after he managed to obtain all the necessary passwords from colleagues, he had to transfer the files to an external storage device. This was not a matter of simply using a thumb drive because, unlike in caper movies such as Mission Impossible, the ports on the computers at the NSA were ordinarily sealed shut. This measure was done specifically to prevent any unauthorized downloading by NSA workers. The only people at the Center who had the authorization, and the means, to open these ports and transfer data were system administrators, according to the former Booz Allen executive. System administrators needed to have this privilege to deal with glitches in the computers. So they were allowed to open up the sealed ports. But Snowden was no longer a system administrator and did not have these privileges. So again, he needed some help. He e
