PostgreSQL + Unattended by TrapTech is a honeypot scenario designed to lure and detect potential attackers in an organization's network. It consists of a honeypot file named Unattended.xml that stores database login data, along with a PostgreSQL database requiring correct login credentials. The Unattended.xml file mimics those used by administrators for automating operating system installations, potentially exposing login account data due to accidental security flaws.
