While doing my job, I learned that fiber optic cables from the secret room were tapping into the Worldnet circuits by splitting off a portion of the light signal. I saw this in a design document available to me, entitled “Study Group 3, LGX/Splitter Wiring, San Francisco” dated Dec. 10, 2002. I also saw design documents dated Jan. 13, 2004 and Jan. 24, 2003, which instructed technicians on connecting some of the already in-service circuits to the “splitter” cabinet, which diverts some of the light signal to the secret room. The circuits listed were the Peering Links, which connect Worldnet with other networks and hence the whole country, as well as the rest of the world.
One of the documents listed the equipment installed in the secret room, and this list included a Narus STA 6400, which is a “Semantic Traffic Analyzer.” The Narus STA technology is known to be used particularly by government intelligence agencies because of its ability to sift through large amounts of data looking for preprogrammed targets. The company’s advertising boasts that its technology “captures comprehensive customer usage data … and transforms it into actionable information.... [It] provides complete visibility for all internet applications.”
