evil-winrm-py 0.0.9

Execute commands interactively on remote Windows machines using the WinRM protocol

evil-winrm-py

evil-winrm-py is a python-based tool for executing commands on remote Windows machines using the WinRM (Windows Remote Management) protocol. It provides an interactive shell.

[!NOTE] This tool is designed strictly for educational, ethical use, and authorized penetration testing. Always ensure you have explicit authorization before accessing any system. Unauthorized access or misuse of this tool is both illegal and unethical.

Motivation

The original evil-winrm is written in Ruby, which can be a hurdle for some users. Rewriting it in Python makes it more accessible and easier to use, while also allowing us to leverage Python’s rich ecosystem for added features and flexibility.

I also wanted to learn more about winrm and its internals, so this project will also serve as a learning experience for me.

Features

• Execute commands on remote Windows machines via an interactive shell.
• Support for NTLM authentication.
• Support for Pass-the-Hash authentication.
• Support for Certificate authentication.
• Support for Kerberos authentication with SPN (Service Principal Name) prefix and hostname options.
• Support for SSL to secure communication with the remote host.
• Support for custom WSMan URIs.
• Download files from the remote host to the local machine.
• Auto-complete remote file and directory paths.
• Enable logging and debugging for better traceability.
• Navigate command history using up/down arrow keys.
• Display colorized output for improved readability..
• Lightweight and Python-based for ease of use.
• Keyboard Interrupt (Ctrl+C) support to terminate long-running commands gracefully.

Installation (Windows/Linux)

Installation of Kerberos prerequisites on Linux

sudo apt install gcc python3-dev libkrb5-dev
# Optional: krb5-user

Install evil-winrm-py

You may use pipx or uv instead of pip to install evil-winrm-py. pipx/uv is a tool to install and run Python applications in isolated environments, which helps prevent dependency conflicts by keeping the tool's dependencies separate from your system's Python packages.

pip install evil-winrm-py
pip install evil-winrm-py[kerberos] # for kerberos support on Linux

or if you want to install with latest commit from the main branch you can do so by cloning the repository and installing it with pip/pipx/uv:

git clone https://github.com/adityatelange/evil-winrm-py
cd evil-winrm-py
pip install .

Update

pip install --upgrade evil-winrm-py

Uninstall

pip uninstall evil-winrm-py
