ADCSKiller – An ADCS Exploitation Automation Tool

ADCSKiller is a Python-based tool designed to automate the process of discovering and exploiting Active Directory Certificate Services (ADCS) vulnerabilities.

It leverages the features of Certipy and Coercer to simplify the process of attacking ADCS infrastructure.

Please note that the ADCSKiller is currently in its first draft and will undergo further refinements and additions in future updates.

Features

• Enumerate Domain Administrators via LDAP
• Enumerate domain controllers via LDAP
• Enumerate Certificate Authorities via Certipy
• Exploitation of ESC1
• Exploitation of ESC8

Installation

Since this tool relies on Certipy and Coercer, both tools have to be installed first.

git clone https://github.com/ly4k/Certipy && cd Certipy && python3 setup.py install
git clone https://github.com/p0dalirius/Coercer && cd Coercer && pip install -r requirements.txt && python3 setup.py install
git clone https://github.com/grimlockx/ADCSKiller/ && cd ADCSKiller && pip install -r requirements.txt

Usage

Usage: adcskiller.py [-h] -d DOMAIN -u USERNAME -p PASSWORD -t TARGET -l LEVEL -L LHOST

Options:
-h, --help Show this help message and exit.
-d DOMAIN, --domain DOMAIN
                        Target domain name. Use FQDN
-u USERNAME, --username USERNAME
                        Username.
-p PASSWORD, --password PASSWORD
                        Password.
-dc-ip TARGET, --target TARGET
                        IP Address of the domain controller.
-L LHOST, --lhost LHOST
                         FQDN of the listener machine - An ADIDNS is probably required

Todos

• Tests, Tests, Tests
• Enumerate the principals which are allowed to dcsync
• Use dirkjanm’s gettgtpkinit.py to receive a ticket instead of Certipy auth
• Support DC Certificate Authorities
• ESC2–ESC7
• ESC9 or ESC11?
• Automated add an ADIDNS entry if required
• Support DCSync functionality
