How Embassy Eavesdropping Works Posted: October 28, 2013 Secret US espionage activity against Germany, from Germany and revealed this week by *Der Spiegel*<http://www.spiegel.de/international/germany/cover-story-how-nsa-spied-on-merkel-cell-phone-from-berlin-embassy-a-930205.html> has added new evidence to European concerns about the interception of the phones of the Germany’s Chancellor Merkel and other world leaders. Duncan was a consultant to *Der Spiegel* for the inquiry and identified the listening “windows” shown on the front cover. Similar, top secret listening installations, protected from scrutiny by diplomatic immunity are used to conduct massive electronic listening, usually from the top floors of US embassies. One is in Berlin. Others are located in European capitals from Stockholm to Athens.<http://www.duncancampbell.org/content/embassy-spy-centre-network> . Duncan filmed inside a similar decommissioned British surveillance facility using the same techniques as the US and UK currently use to spy in Europe’s capital cities. His investigations led to a 1999 television expose<http://duncancampbell.org/embassy-bugging#capenhurst> about how the UK had secretly intercepted and analysed all the international communications of the Irish Republic, an EU member. GCHQ’s activities were later found to be unlawful by the European Court of Human Rights. *How embassy eavesdropping works* *The key visible feature of most embassy and diplomatic sites that give away their secret spying missions are large windowless areas on top floors, and also sheds or hangers on the roof which are designed to look as though they might contain lift or air conditioning apparatus. * *At the US Embassy in Berlin, the lighter colored panels on the south west, north west and northeast corners of the rooftop surveillance facility are dielectric “radio windows” which allow all types of radio signals to reach collection and analysis equipment on the roof and floor directly below.* *The “radio window” panels are made of special material which does not conduct electricity. That is so weak radio signals coming in from all corners of the city are not diminished (attenuated) as they pass into the building and reach the sigint (signals intelligence) antennae.* *Usually, dielectric window panels for signals intelligence work are made of plastic or fiberglass. They are often shaped and colored to look as though they are a normal part of the building, or are special architectural features.* [image: External Close up of Radio window panel at Capenhuirst] *Hidden behind the panels are a range of special monitoring antenna, dishes or arrays which collect every type of commercial and civil mobile, and government communications, including internet traffic, on all available wavelengths.* *Rooftop “sheds” like in Berlin can be seen on dozens of US embassies in Europe and around the world, except in “Five Eyes” allied countries such as the UK. Apart from the “collection” sheds, large processing areas are needed to analyse and transmit the result of interception to the global surveillance network. * *Windowless top floors, such on the south wing of the Berlin embassy provide “SCIFs” – Secure Compartmented Intelligence Facilities – which are needed to prevent any radio signals from the interception and analysis equipment themselves leaking out. The processing operators and equipment for the “Special Collection Service” are sited in these rooms.* *The largest and most obvious US diplomatic surveillance facility in Europe is on the roof of the Geneva consulate, overlooking the United Nations. The Berlin eavesdropping facility is one of the largest, comparable in size to those in sensitive Middle East locations such as Yemen or Cyprus. * *When the former GCHQ surveillance installation in Capenhurst in northern England was retired from service and put up for sale (TV link), it was possible to inspect inside and see what the embassy surveillance center might look like.* *The 150 ft (50 meter tower had been placed directly between two British Telecom microwave radio towers carrying telephone traffic. It was the ideal place to discreetly intercept international telephone calls of the Irish government, businessmen and also those of suspected of involvement with IRA terrorism.* *The hi-tech tower included eight floors of advanced electronic equipment and three floors of aerial galleries. These were used to extract and sort the thousands of communications passing through every hour.* __._ __,_._,___ -- -- Thanks for being part of "PoliticalForum" at Google Groups.
