pwntools - CTF toolkit

[Aerosol]

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 for hexdump with colors.
  

Installation

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 pwntools

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