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

What are the services running on the target machine?


Now you are familiar with how to scan the IP address and identify a live host within a subnet. In this section, we will discuss the services that are running on a host. These services are the ones that are using a network connection. The service using a network connection must open a port; from a port number, we can identify which service is running on the target machine. In pentesting, the significance of port scanning is to check whether any illegitimate service is running on the host machine.

Consider a situation where users normally use their computer to download a game, and a Trojan is identified during the installation of the game. The Trojan goes into hidden mode and opens a port and sends all the keystrokes log information to the hacker. In this situation, port scanning helps to identify the unknown services that are running on the victim's computer.

Port numbers range from 0 to 65536.The well-known ports (also known as system ports...
