BloodHound

BloodHound

BloodHound is an application developed to find relationships within an Active Directory (AD) and to discover attack paths. It does this by using graph theory to find the shortest path an attacker needs to take to elevate their privileges within the domain.

BloodHound is developed by @_wald0, @CptJesus, et @harmj0y.

BloodHound is based on neo4j, which must therefore be installed and launched before using BlooHound.

Bloodhound has become BloodHound CE and the GitHub repo has changed

Windows

Install neo4j :

1. Download neo4j Community Server Edition zip from https://neo4j.com/download-center/#community.

2. Unzip the neo4j zip file.

3. Open a command prompt, as an administrator.

4. Change directory to reach the unzipped neo4j folder.

5. Change the directory to the bin directory in the Neo4j folder.

neo4j.bat install-service

Launch neo4j :

net start neo4j

Unix

Install neo4j :

sudo apt install neo4j

Launch neo4j :

sudo systemctl start neo4j 

There are several Ingestor for Bloodhound:

• SharpHound.exe (Official)

• SharpHound.ps1 (Official)

• Python-Bloodhound

Not all support the same methods, choose your Ingestor wisely.

It is important to note that Sharphound can be run from a computer that is not enrolled in the AD domain, by running it in a domain user context using Runas, Pass-The-Hash (PTH) or Pass-The-Ticket(PTT)

Windows CMD

# From a non enrolled machine 
SharpHound.exe -c all -d <DOMAIN> --ldapusername <USERNAME> --ldappassword "<PASSWORD>"

# or 
runas /netonly /user:DOMAIN\USERNAME cmd.exe
SharpHound.exe -d <DOMAIN>

Windows Powershell

# Import SharpHound.ps1 module
. .\SharpHound.ps1

# Use the Invoke-Bloodhound function  
Invoke-BloodHound -c All -d <DOMAIN> --ldapusername <USERNAME> --ldappassword "<PASSWORD>"

BloodHound est très peu discret dans un réseau, vous pouvez donc utiliser cette option pour éviter la détection par l'ATA (Advanced Threat Analytics) par exemple :

Invoke-BloodHound -c All -d <DOMAIN> --ldapusername <USERNAME> --ldappassword "<PASSWORD>" --excludedcs

UNIX

From experience, python-bloodhound is much faster than SharpHound.exe and .ps1. It then becomes useful in a large Active Directory with many users and machines.

python3 bloodhound.py -c all -u <USERNAME>-p <PASSWORD> -d <DOMAIN> --zip
