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

Effects of parameter tampering on business


As a pentester, you will often have to analyze the source code. These days, the world of e-commerce is growing quickly. Consider an example of an e-commerce website, as shown in the following screenshot:

Example of a website

The preceding screenshot shows that the price of a Nokia C7 is 60 and the price of an iPhone 3G is 600. You do not know whether these prices came from the database or are written in the web page. The following screenshot shows the price of both mobiles:

Now, let's look at the source code, as shown in the following screenshot:

Look at the rectangular boxes in the preceding screenshot. The price 60 is written in the web page, but the price 600 is taken from the database. The price 60 can be changed by URL tampering if the GET method is used. The price can be changed to 6 instead of 60. This will badly impact the business. In white-box testing, the client gives you the source code, and you can analyze this code, but...
