Python: Penetration Testing for Developers

By: Christopher Duffy, Mohit , Cameron Buchanan, Andrew Mabbitt, Terry Ip, Dave Mound, Benjamin May

Overview of this book

Cybercriminals are always one step ahead, when it comes to tools and techniques. This means you need to use the same tools and adopt the same mindset to properly secure your software. This course shows you how to do just that, demonstrating how effective Python can be for powerful pentesting that keeps your software safe. Comprising of three key modules, follow each one to push your Python and security skills to the next level. In the first module, we’ll show you how to get to grips with the fundamentals. This means you’ll quickly find out how to tackle some of the common challenges facing pentesters using custom Python tools designed specifically for your needs. You’ll also learn what tools to use and when, giving you complete confidence when deploying your pentester tools to combat any potential threat. In the next module you’ll begin hacking into the application layer. Covering everything from parameter tampering, DDoS, XXS and SQL injection, it will build on the knowledge and skills you learned in the first module to make you an even more fluent security expert. Finally in the third module, you’ll find more than 60 Python pentesting recipes. We think this will soon become your trusted resource for any pentesting situation. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ? Learning Penetration Testing with Python by Christopher Duffy ? Python Penetration Testing Essentials by Mohit ? Python Web Penetration Testing Cookbook by Cameron Buchanan,Terry Ip, Andrew Mabbitt, Benjamin May and Dave Mound

Testing for insecure cookie flags


The next topic of interest from the HTTP protocol is cookies. As HTTP is a stateless protocol, cookies provide a way to store persistent data on the client side. This allows a web server to have session management by persisting data to the cookie for the length of the session.

Cookies are set from the web server in the HTTP response using a Set-Cookie header. They are then sent back to the server through the Cookie header. This recipe will look at ways to audit the cookies being set by a website to verify if they have secure attributes or not.

How to do it…

The following is a recipe to enumerate through each of the cookies set on a target site and flag any insecure settings that are present:

import requests

req = requests.get('http://www.packtpub.com')
for cookie in req.cookies:
  print 'Name:', cookie.name
  print 'Value:', cookie.value

  if not cookie.secure:
    cookie.secure = '\x1b[31mFalse\x1b[39;49m'
  print 'Secure:', cookie.secure

  if 'httponly...
