What is this?BloodHound Legacy is a security tool that uses graph theory to map hidden relationships and attack paths inside an Active Directory environment, helping find the shortest route to Domain Admin — hence its tagline 'Six Degrees of Domain Admin'.
Is this a command-line scanner or a visual app?It's a desktop GUI application built on Electron (its start:client script literally launches 'electron .'), designed to visually explore the attack-path graph built from data collected in an Active Directory environment.
Should I install this version?No — this repository is deprecated and will be archived soon; you should install the new BloodHound Community Edition instead, which has its own repository, installation instructions, and documentation.
Is this version still maintained?No. It was last updated in 2023, is no longer maintained, and the maintainers say it will be archived in the near future.
What does 'Six Degrees of Domain Admin' mean?It describes BloodHound's core idea: using graph analysis to surface short, often-overlooked chains of relationships that let an attacker escalate from an ordinary user all the way to Domain Admin.
What is BloodHound Enterprise?It's SpecterOps' commercial Attack Path Management product that continuously maps and quantifies Active Directory attack paths, aiming to eliminate the techniques attackers rely on most.
Can I still read the old documentation?Yes — the deprecated BloodHound Legacy documentation remains linked and accessible from the README even though the tool itself is no longer maintained.
