Pwntools is a CTF framework and exploit development library. Written in Python, it is designed for rapid prototyping and development, and intended to make exploit writing as simple as possible.

from pwn import *
context(arch = 'i386', os = 'linux')

r = remote('exploitme.example.com', 31337)
# EXPLOIT CODE GOES HERE
r.send(asm(shellcraft.sh()))
r.interactive()

Documentation

Our documentation is available at docs.pwntools.com

A series of tutorials is also available online

To get you started, we've provided some example solutions for past CTF challenges in our write-ups repository.

Installation

Pwntools is best supported on 64-bit Ubuntu LTS releases (22.04 and 24.04). Most functionality should work on any Posix-like distribution (Debian, Arch, FreeBSD, OSX, etc.).

Pwntools supports Python 3.10+ since version 5.0.0. Use Pwntools 4.x for older versions as well as Python 2.7. Most of the functionality of pwntools is self-contained and Python-only. You should be able to get running quickly with

sudo apt-get update
sudo apt-get install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade pwntools

However, some of the features (assembling/disassembling foreign architectures) require non-Python dependencies. For more information, see the complete installation instructions here.
