Python Penetration Testing Cookbook

By: Rejah Rehim

Overview of this book

Penetration testing is the use of tools and code to attack a system in order to assess its vulnerabilities to external threats. Python allows pen testers to create their own tools. Since Python is a highly valued pen-testing language, there are many native libraries and Python bindings available specifically for pen-testing tasks. Python Penetration Testing Cookbook begins by teaching you how to extract information from web pages. You will learn how to build an intrusion detection system using network sniffing techniques. Next, you will find out how to scan your networks to ensure performance and quality, and how to carry out wireless pen testing on your network to avoid cyber attacks. After that, we’ll discuss the different kinds of network attack. Next, you’ll get to grips with designing your own torrent detection program. We’ll take you through common vulnerability scenarios and then cover buffer overflow exploitation so you can detect insecure coding. Finally, you’ll master PE code injection methods to safeguard your network.

Creating a packet with Scapy

As we know, the basic unit of network communication is a packet. So we can start by creating a packet with Scapy. Scapy creates packets in layers; each layer is nested inside its parent layer.

Getting ready

As we require a Scapy module to be installed in the environment, make sure to install it with the pip command:

pip install scapy  

After installation, make sure it's working by issuing the scapy command in your Terminal:

scapy
Welcome to Scapy (3.0.0)
>>>  

This will open up an interactive Terminal for Scapy. You can also use this for basic debugging of Scapy scripts. A list of all the protocols supported by Scapy is as follows:

>>> ls()  

Similarly, we can get the details...
