linWinPwn is a bash script that automates a number of Active Directory Enumeration and Vulnerability checks. The script leverages and is dependent of a number of tools including: impacket, bloodhound, crackmapexec, ldapdomaindump, lsassy, smbmap, kerbrute, adidnsdump.

Setup

Git clone the repository and make the script executable

git clone https://github.com/lefayjey/linWinPwn
cd linWinPwn; chmod +x linWinPwn.sh

Install Linux and Python packages

sudo apt update
sudo apt install python3 python3-dev python3-pip python3-venv nmap smbmap john libsasl2-dev libldap2-dev ntpdate -y
sudo pip install -r requirements.txt
wget -q "https://raw.githubusercontent.com/micahvandeusen/gMSADumper/main/gMSADumper.py" -O ./Scripts/gMSADumper.py

wget -q "https://raw.githubusercontent.com/ropnop/windapsearch/master/windapsearch.py" -O ./Scripts/windapsearch.py

On non-Kali machines, uncomment the lines under #Non-Kali variables and run the following commands

sudo pip install impacket crackmapexec
mkdir -p wordlists && wget https://raw.githubusercontent.com/danielmiessler/SecLists/master/Passwords/Leaked-Databases/rockyou.txt.tar.gz -O ./wordlists/rockyou.txt.tar.gz && gunzip ./wordlists/rockyou.txt.tar.gz && tar xf ./wordlists/rockyou.txt.tar -C ./wordlists/ && chmod 644 ./wordlists/rockyou.txt && rm ./wordlists/rockyou.txt.tar && wget https://raw   .githubusercontent.com/danielmiessler/SecLists/master/Usernames/cirt-default-usernames.txt -O ./wordlists/cirt-default-usernames.txt

If you're having DNS issues, run the update_dns script WARNING: The script will update /etc/resolv.conf, make sure to backup it before running the script

chmod +x update_dns.sh
sudo ./update_dns.sh <DC_IP>

Usage

Modules

The linWinPwn script contains 4 modules that can be used either separately or simultaneously.

Default (fastest): ad_enum,kerberos with OPSEC safe checks using -O

./linWinPwn.sh -O -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP> -o <output_dir>

User modules: ad_enum,kerberos,scan_shares,vuln_checks,mssql_enum

./linWinPwn.sh -M user -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP> -o <output_dir>

All modules: ad_enum,kerberos,scan_shares,vuln_checks,mssql_enum,pwd_dump

./linWinPwn.sh -M all -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP> -o <output_dir>

Module ad_enum: Active Directory Enumeration

./linWinPwn.sh -M ad_enum -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP_or_Target_Domain> -o <output_dir>

Module kerberos: Kerberos Based Attacks

./linWinPwn.sh -M kerberos -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP_or_Target_Domain> -o <output_dir>

Module scan_shares: Network Shares Scan

./linWinPwn.sh -M scan_shares -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]>  -t <Domain_Controller_IP_or_Target_Domain> -o <output_dir>

Module vuln_checks: Vulnerability Checks

./linWinPwn.sh -M vuln_checks -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]>  -t <Domain_Controller_IP_or_Target_Domain> -o <output_dir>

Module mssql_enum: MSSQL Enumeration

./linWinPwn.sh -M mssql_enum -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]>  -t <Domain_Controller_IP_or_Target_Domain> -o <output_dir>

Module pwd_dump: Password Dump

./linWinPwn.sh -M pwd_dump -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]>  -t <Domain_Controller_IP_or_Target_Domain> -S <domain_servers_list> -o <output_dir>
