Former AT&T technician Mark Klein is the key witness in the Electronic Frontier Foundation's class-action lawsuit against the telecommunications company, which alleges that AT&T cooperated in an illegal National Security Agency domestic surveillance program.
In a public statement Klein issued last month, he described the NSA's visit to an AT&T office. In an older, less-public statement recently acquired by Wired News, Klein goes into additional details of his discovery of an alleged surveillance operation in an AT&T building in San Francisco.
Three pages long. Lots of links. Spilling beans all over the place. This from a document he wrote in December, 2004:
In 2003 AT&T built "secret rooms" hidden deep in the bowels of its central offices in various cities, housing computer gear for a government spy operation which taps into the company's popular WorldNet service and the entire internet. These installations enable the government to look at every individual message on the internet and analyze exactly what people are doing.Documents showing the hardwire installation in San Francisco suggest that there are similar locations being installed in numerous other cities.
The physical arrangement, the timing of its construction, the government-imposed secrecy surrounding it and other factors all strongly suggest that its origins are rooted in the Defense Department's Total Information Awareness (TIA) program which brought forth vigorous protests from defenders of constitutionally protected civil liberties last year...
...
Plans for the "secret room" were fully drawn up by December 2002, curiously only four months after Darpa started awarding contracts for TIA. One 60-page document, identified as coming from "AT&T Labs Connectivity & Net Services" and authored by the labs' consultant Mathew F. Casamassima, is titled Study Group 3, LGX/Splitter Wiring, San Francisco and dated 12/10/02. This document addresses the special problem of trying to spy on fiber-optic circuits. Unlike copper wire circuits which emit electromagnetic fields that can be tapped into without disturbing the circuits, fiber-optic circuits do not "leak" their light signals. In order to monitor such communications, one has to physically cut into the fiber somehow and divert a portion of the light signal to see the information.
This problem is solved with "splitters" which literally split off a percentage of the light signal so it can be examined. This is the purpose of the special cabinet referred to above: Circuits are connected into it, the light
signal is split into two signals, one of which is diverted to the "secret room." The cabinet is totally unnecessary for the circuit to perform -- in fact it introduces problems since the signal level is reduced by the splitter -- its only purpose is to enable a third party to examine the data flowing between sender and recipient on the internet.
Too technical for me, but it doesn't seem to pass the smell test.
I report.
You decide.

The key question is does this stuff, these places, as described, really exist? I've met more than a few people who are pretty convincing in their stories, but who are actually just plain crazy or lying for notoriety or financial gain. I don't know, either, but if these "secret rooms" and "splitter cabinets" exist, then they can be seen, touched, and the evidence corroborated. Otherwise, given the lack of factual basis for so much "news", these days and the fact that the volume of information the government would have to slog through would be completely unmanageable, I'll remain skeptical.
