synacktiv/gpoddityAutomates Active Directory GPO exploitation via NTLM relaying, enabling malicious GPO template generation, location spoofing, and command execution for privilege escalation and lateral movement.
The GPOddity project, aiming at automating GPO attack vectors through NTLM relaying (and more).
For more details regarding the attack and a demonstration on how to use the tool, see the associated article available at: https://www.synacktiv.com/publications/gpoddity-exploiting-active-directory-gpos-through-ntlm-relaying-and-more
You can install GPOddity through pipx with the following command:
$ python3 -m pipx install git+https://github.com/synacktiv/GPOddity
Alternatively, you can install GPOddity manually by cloning the repository and installing the dependencies:
$ git clone https://github.com/synacktiv/GPOddity
$ python3 -m pip install -r requirements.txt
$ python3 gpoddity.py --help
Usage: gpoddity.py [OPTIONS]
