Autobloody – Tool To Automatically Exploit Active Directory Privilege Escalation Paths Shown By BloodHound

autobloody is a tool to automatically exploit Active Directory privilege escalation paths shown by BloodHound.


This tool automates the AD privesc between two AD objects, the source (the one we own) and the target (the one we want) if a privesc path exists in BloodHound database. The automation is composed of two steps:

  • Finding the optimal path for privesc using bloodhound data and neo4j queries.
  • Execute the path found using bloodyAD package

Because autobloody relies on bloodyAD, it supports authentication using cleartext passwords, pass-the-hash, pass-the-ticket or certificates and binds to LDAP services of a domain controller to perform AD privesc.


First if you run it on Linux, you must have libkrb5-dev installed on your OS in order for kerberos to work:

# Debian/Ubuntu/Kali
apt-get install libkrb5-dev

# Centos/RHEL
yum install krb5-devel

# Fedora
dnf install krb5-devel

# Arch Linux
pacman -S krb5

A python package is available:

pip install autobloody

Or you can clone the repo:

git clone --depth 1
pip install .


  • bloodyAD
  • Neo4j python driver
  • Neo4j with the GDS library
  • BloodHound
  • Python 3
  • Gssapi (linux) or Winkerberos (Windows)

How to use it

First data must be imported into BloodHound (e.g using SharpHound or and Neo4j must be running.

-ds and -dt values are case sensitive

Simple usage:

Full help:

[bloodyAD]$ ./ -h
usage: [-h] [--dburi DBURI] [-du DBUSER] -dp DBPASSWORD -ds DBSOURCE -dt DBTARGET [-d DOMAIN] [-u USERNAME] [-p PASSWORD] [-k] [-c CERTIFICATE] [-s] --host HOST

AD Privesc Automation

-h, --help show this help message and exit
--dburi DBURI The host neo4j is running on (default is "bolt://localhost:7687")
-du DBUSER, --dbuser DBUSER
Neo4j username to use (default is "neo4j")
Neo4j password to use
-ds DBSOURCE, --dbsource DBSOURCE
Case sensitive label of the source node (name property in bloodhound)
-dt DBTARGET, --dbtarget DBTARGET
Case sensitive label of the target node (name property in bloodhound)
-d DOMAIN, --domain DOMAIN
Domain used for NTLM authentication
-u USERNAME, --username USERNAME
Username used for NTLM authentication
-p PASSWORD, --password PASSWORD
Cleartext password or LMHASH:NTHASH for NTLM authentication
-k, --kerberos
Certificate authentication, e.g: "path/to/key:path/to/cert"
-s, --secure Try to use LDAP over TLS aka LDAPS (default is LDAP)
--host HOST Hostname or IP of the DC (ex: my.dc.local or

How it works

First a privesc path is found using the Dijkstra’s algorithm implemented into the Neo4j’s GDS library. The Dijkstra’s algorithm allows to solve the shortest path problem on a weighted graph. By default the edges created by BloodHound don’t have weight but a type (e.g MemberOf, WriteOwner). A weight is then added to each edge accordingly to the type of edge and the type of node reached (e.g user,group,domain).

Once a path is generated, autobloody will connect to the DC and execute the path and clean what is reversible (everything except ForcePasswordChange and setOwner).


For now, only the following BloodHound edges are currently supported for automatic exploitation:

  • MemberOf
  • ForceChangePassword
  • AddMembers
  • AddSelf
  • DCSync
  • GetChanges/GetChangesAll
  • GenericAll
  • WriteDacl
  • GenericWrite
  • WriteOwner
  • Owns
  • Contains
  • AllExtendedRights
