linWinPwn

linWinPwn is a bash script written by lefayjey that automates several Active Directory Enumeration and Vulnerability checks. The script uses several tools such as: impacket, bloodhound, crackmapexec, ldapdomaindump, lsassy, smbmap, kerbrute, adidnsdump, certipy, and others. Red Teams find this tool particularly useful when you have access to an Active Directory environment for a limited time only and wish to automate the enumeration process and efficiently collect evidence. In addition, linWinPwn can replace the use of enumeration tools on Windows to reduce the number of created artifacts and bypass certain Anti-Virus or EDRs. This can be achieved by performing remote dynamic port forwarding through the creation of an SSH tunnel from the Windows host (e.g., VDI machine or workstation or laptop) to a remote Linux machine (e.g., Pentest laptop or VPS), and running linWinPwn with proxychains.

On the Windows host, run using PowerShell:

ssh kali@<linux_machine> -R 1080 -NCqf

proxychains ./linWinPwn.sh -t <Domain_Controller_IP>

Setup

Git clone the repository and make the script executable

git clone https://github.com/lefayjey/linWinPwn

cd linWinPwn; chmod +x linWinPwn.sh

Install requirements on Kali machines using the install.sh script

chmod +x install.sh

sudo ./install.sh

On non-Kali machines, run the install_nonkali.sh script instead

chmod +x install_nonkali.sh

sudo ./install_nonkali.sh

If you’re having DNS issues or time sync errors, run the configure.sh script with -d for DNS update and -n for NTP sync

chmod +x configure.sh

sudo ./configure.sh -t -d -n

Usage

Modules

The linWinPwn script contains 6 modules that can be used either separately or simultaneously.
