Fallingbostel, the train station where they get off the train (and which isn't actually Fallingbostel) used to be the location of a world renowned annual international demoscene (underground computer arts) party, Mekka & Symposium. The location is likely a nod to this event. The movie was screened publicly at Mekka & Symposium after its release, and the audience cheered at this scene.
In order to establish first contact with the Soviet secret service, three young men, named Karl Koch alias "Hagbard Celine", Dirk Otto B. alias "DOB", and Peter C. alias "Pedro", drove to East Berlin in September 1986. At first, they were ignored by the Soviets, but then they found an agent who recognized the potential of such attacks. His code name was "Sergei". Over the following two years, the hackers delivered all kinds of programs and huge amounts of data to the KGB. The Soviet organization paid a total of 90,000 Deutsche Mark to the group.
