Although you can run Neo4j and BloodHound on different machines with some more setup, its easiest to just run both on the same machine. It needs to be run on an endpoint to do this, as there are two flavours (technically three if we include the python ingestor) well want to drop either the PowerShell version or the C# binary onto the machine to enumerate the domain. Enter the user as the start node and the domain admin group as the target. 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. SharpHound is written using C# 9.0 features. Delivery: Estimated between Tue, Mar 7 and Sat, Mar 11 to 23917. Whenever SENMAN00282 logs in, you will get code execution as a Domain Admin account.
