This is the CTF framework used by Gallopsled in every CTF.
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()However we have made command-line frontends for some of the functionality
in pwnlib. These are:
asm/disasm: Small wrapper for various assemblers.constgrep: Tool for finding constants defined in header files.cyclic: De Bruijn sequence generator and lookup tool.hex/unhex: Command line tools for doing common hexing/unhexing operations.shellcraft: Frontend to our shellcode.phd: Replacement forhexdumpwith colors.
Our documentation is available at pwntools.readthedocs.org
To get you started, we've provided some example solutions for past CTF challenges in our write-ups repository.
pwntools is best supported on Ubuntu 12.04 and 14.04, but most functionality should work on any Posix-like distribution (Debian, Arch, FreeBSD, OSX, etc.).
Most of the functionality of pwntools is self-contained and Python-only. You should be able to get running quickly with
pip install pwntoolsHowever, some of the features (ROP generation and assembling/disassembling foreign architectures) require non-Python dependencies. For more information, see the complete installation instructions here.
