Remember how we set our Neo4j password through the web interface at localhost:7474? There are also others such as organizational units (OUs) and Group Policy Objects (GPOs) which extend the tools capabilities and help outline different attack paths on a domain. For detailed and official documentation on the analysis process, testers can check the following resources: Some custom queries can be used to go even further with the analysis of attack paths, such as, Here are some examples of quick wins to spot with BloodHound, : users that are not members of privileged Active Directory groups but have sensitive privileges over the domain (run graph queries like "find principals with, rights", "users with most local admin rights", or check "inbound control rights" in the domain and privileged groups node info panel), ) and that often leads to admins, shadow admins or sensitive servers (check for "outbound control rights" in the node info panel), (run graph queries like "find computer with unconstrained delegations"), : find computers (A) that have admin rights against other computers (B). You may want to reset one of those users credentials so you can use their account, effectively achieving lateral movement to that account. Run pre-built analytics queries to find common attack paths, Run custom queries to help in finding more complex attack paths or interesting objects, Mark nodes as high value targets for easier path finding, Mark nodes as owned for easier path finding, Find information about selected nodes: sessions, properties, group membership/members, local admin rights, Kerberos delegations, RDP rights, outbound/inbound control rights (ACEs), and so on, Find help about edges/attacks (abuse, OPSEC considerations, references), Using BloodHound can help find attack paths and abuses like.
