Defensive OSINT

Defensive OSINT is typically used to see what has already been breached and see whether that information is valuable during the penetration testing activity. If the goal of the penetration testing is to demonstrate a real-world scenario, this data can be handy, and the first step is to identify a similar target that has been already breached. The majority of organizations fix only the affected platform or the host, and they often forget about other similar environments. Defensive OSINT is largely divided into three places of search.
