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

Brute forcing login through the Authorization header


Many websites use HTTP basic authentication to restrict access to content. This is especially prevalent in embedded devices such as routers. The Python requests library has built-in support for basic authentication, making an easy way to create an authentication brute force script.

Getting ready

Before creating this recipe, you're going to need a list of passwords to attempt to authenticate with. Create a local text file called passwords.txt, with each password on a new line. Check out Brute forcing passwords in Chapter 2, Enumeration, for password lists from online resources. Also, spend some time to scope out the target server as you're going to need to know how it responds to a failed login request, so that we can differentiate when the brute force works or not.

How to do it…

The following code will attempt to brute force entry to website through basic authentication:

import requests
from requests.auth import HTTPBasicAuth

with open('passwords...
