# BloodHound

### **BloodHound**

[BloodHound ](https://github.com/BloodHoundAD/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 ](https://github.com/BloodHoundAD/BloodHound)is developed by  [@\_wald0](https://www.twitter.com/_wald0), [@CptJesus](https://twitter.com/CptJesus), **et** [@harmj0y](https://twitter.com/harmj0y).

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

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.

```powershell
neo4j.bat install-service
```

**Launch neo4j :** 

```powershell
net start neo4j
```

{% endtab %}

{% tab title="Unix" %}

{% hint style="warning" %}
There are several Ingestor for Bloodhound:

* [SharpHound.exe](https://github.com/BloodHoundAD/BloodHound/blob/master/Collectors/SharpHound.exe) (Official)
* [SharpHound.ps1](https://github.com/BloodHoundAD/BloodHound/blob/master/Collectors/SharpHound.ps1) (Official)
* [Python-Bloodhound](https://github.com/fox-it/BloodHound.py)

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)
{% endhint %}

{% tabs %}
{% tab title="Windows CMD" %}

```powershell
# 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>
```

{% endtab %}

{% tab title="Windows Powershell" %}

```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 :

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

{% endtab %}

{% tab title="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.

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

{% endtab %}
{% endtabs %}
