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.

Memory dump

We can easily view the contents of a memory location with the memory dump. We can use Immunity Debugger or pwndbg for this.

How to do it...

Follow the steps for better understanding of memory dump:

  1. Open an application in the Immunity Debugger.
  1. If you want to view the memory dump in ESI register and right-click on the address and select the Follow in Dump option:
  1. This will update the memory dump window in the bottom-left corner. The memory dump window in Immunity Debugger looks as follows:
  1. With pwndbg we can get the memory dump with the hexdump command. For that, load the application in gdb and run it with a breaker:
pwndbg> break 5
pwndbg> run  
  1. Now to view the memory dump in RSI register, run...
