bloodyAD

bloodyAD.py is an Active Directory privilege escalation swiss army knife

Description

This tool can perform specific LDAP/SAMR calls to a domain controller in order to perform AD privesc.

bloodyAD 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.

It is designed to be used transparently with a SOCKS proxy.

Installation

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 bloodyAD
bloodyAD --host 172.16.1.15 -d bloody.local -k set password john.doe 'Password123!'

Or you can clone the repo:

git clone --depth 1 https://github.com/CravateRouge/bloodyAD
pip install .
bloodyAD --host 172.16.1.15 -d bloody.local -k set password john.doe 'Password123!'

[bloodyAD]$ bloodyAD --host 172.16.1.15 -d bloody.local -u jane.doe -p :70016778cb0524c799ac25b439bd6a31 set password -h
usage: bloodyAD.py set password [-h] [--oldpass OLDPASS] target newpass

positional arguments:
  target             sAMAccountName, DN, GUID or SID of the target
  newpass            new password for the target

  --oldpass OLDPASS  old password of the target, mandatory if you don't have "change password" permission on the target (default: None)

How it works

bloodyAD communicates with a DC using mainly the LDAP protocol in order to get information or add/modify/delete AD objects. Exchange of sensitive information such as passwords without LDAPS are now supported.
