Room Interception and Secret Perquisition during the State Security

Case Studies on the Implementation and Results of Secret Operation

Abstract

The case study deals with some measures of a confidential investigation against an Austrian businessman. The Hungarian state security service suspected the Austrian man of espionage, so the counterintelligence service kept him under investigation. Counter-espionage used the available secret forces and tools, from the methods of obtaining technical information to the tool system of human intelligence. Their measures
included wiretapping the man’s hotel rooms and telephone conversations, monitoring his movements in the country, employing agents, as well as observing the persons who came into closer contact with the Austrian businessman. Thus, covert listening devices were installed in his doctor friend’s apartment, and another acquaintance was monitored during his vacation.
In the case study, the author presents the methods and procedures used by the state security service to collect certain secret information. It also examines what information was obtained by the counterintelligence department through each of the measures.
