Maximizing BloodHound with a simple suite of tools

Description

New Release:

  • dpat – The BloodHound Domain Password Audit Tool (DPAT)

A simple suite of tools:

  • get-info – Pull lists of information from the Neo4j database
  • mark-owned – Mark a list of objects as Owned
  • mark-hvt – Mark a list of objects as High-Value Targets
  • query – Run a raw Cypher query and return output
  • export – Export all outbound controlling privileges of a domain object to a CSV file
  • del-edge – Delete an edge from the database
  • add-spns – Create HasSPNConfigured relationships, new attack primitive
  • add-spw – Create SharesPasswordWith relationships
  • dpat – The BloodHound Domain Password Audit Tool (DPAT)
  • pet-max – Dogsay, happiness for stressful engagements

This was released with screenshots & use-cases on the following blogs: Max Release, Updates & Primitives & DPAT

A new potential attack primitive was added to this tool during my research, see the add-spns section for full details.
