OSINT (or as it sounds in the full English version of Open Source INTelligence) is a technology for searching, accumulating and analyzing data collected from available sources on the Internet. It sounds too general, so we will try to reveal the essence of the term in a more human language.
Back in 1947, one of the CIA analysts, Ken Sherman, reported that the country collects about 80% of the information from open sources on the network. A little later, the head of the DIA of the United States, Samuel Wilson, said that 90% of intelligence data is also obtained from open sources, and only the remaining 10% come from the professional work of agents and spies. Here is such a modern “James Bond”, enclosed in an Internet search bar.
