It turns out our Soviet Big Brother could be spying on us too. Intelligence historian Matthew Aid discovered through declassified CIA documents that Russia still has a massive network of former KGB listening stations that are actively eavesdropping. And here's where they are.
While some of the old spy outposts are rusting away in disrepair in former Soviet Union countries, many are still alive and well. Foreign Policy has an interactive map that shows the fortresses scattered throughout the Eastern block and Russia, with a little background on each.
The stations were historically used during the Cold War to gather any and all intel they could on the US and its allies. Of course, they were also used to spy on the Soviet Union's very own citizens. Aid explains that they "were a small but very important part of the massive [signals intelligence] intercept and processing complexes operated not only by the KGB but also by the Soviet military intelligence service, the GRU." The Dymovka station, for example, is as far West as the Polish border of Ukraine. Satellite activity suggests it's been taken over by Ukraine's SIGINT organisation. As for the remaining 10 or so stations, head over to Foreign Policy for more info. [Foreign Policy]
