PostgreSQL + Group Policy Preferences by TrapTech is a honeypot scenario designed to attract and detect potential attackers in a network environment. It consists of two main components: a lure in the form of a Group Policy Preferences file storing login data for a database, and a PostgreSQL database that requires correct login credentials. The lure can be placed on Windows workstations and servers, serving as bait for cybercriminals attempting to exploit potential security vulnerabilities.
