Pwntools is a CTF framework and exploit development library for rapid prototyping and writing exploits in Python.
The tool addresses the challenge of building exploits and solving capture-the-flag challenges by providing a comprehensive library that abstracts away low-level details. It handles tasks like shellcode generation, ROP gadget discovery, binary packing and unpacking, and communication with target processes. The library is designed to make exploit writing as simple as possible by offering high-level Python interfaces to common exploit development operations.
Pwntools suits security researchers, CTF competitors, and exploit developers who want to prototype attacks quickly without writing boilerplate code. It works best on 64-bit Ubuntu LTS systems but supports most POSIX-like distributions including Debian, Arch, FreeBSD, and macOS. The core functionality is self-contained and Python-only, though some features like assembling and disassembling foreign architectures require additional non-Python dependencies. The project provides extensive documentation, online tutorials, and a repository of write-ups from past CTF challenges to help new users get started.
The project maintains active community engagement through a Discord server for questions and discussion. Development activity shows consistent attention to supporting multiple Python versions and platforms, with the codebase having evolved to require Python 3.10 or later in recent versions while maintaining a separate branch for older Python 2.7 compatibility. The project accepts contributions and maintains clear guidelines for community involvement through its contribution documentation.
