Python tools for penetration testers

If you are involved in vulnerability research, reverse engineering or pentesting, I suggest to try out the Python programming language. It has a rich set of useful libraries and programs. This page lists some of them.

Most of the listed tools are written in Python, others are just Python bindings for existing C libraries, i.e. they make those libraries easily usable from Python programs.

Some of the more aggressive tools (pentest frameworks, bluetooth smashers, web application vulnerability scanners, war-dialers, etc.) are left out, because the legal situation of these tools is still a bit unclear in Germany -- even after the decision of the highest court. This list is clearly meant to help whitehats, and for now I prefer to err on the safe side.

Network

• Scapy: send, sniff and dissect and forge network packets. Usable interactively or as a library
• pypcap, Pcapy and pylibpcap: several different Python bindings for libpcap
