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.

TCP ACK scanning

ACK flag scanning is useful to verify whether the server is blocked with firewalls, IPS, or other network security controls. As in the FIN scan, we will send an TCP ACK packet. No response or an ICMP error indicates the presence of a stateful firewall, as the port is filtered, and if we get back an RST-ACK, then the stateful firewall is absent:

How to do it...

The steps to create a TCP ACK scanner with Scapy are as following:

  1. As usual, import the required modules and set the variables. Also, define the method to check the status of the host:
from scapy.all import * 
# define the host, port 
host = '' 
ip = socket.gethostbyname(host) 
port = 80 
# define the method to check the status...
