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.

Sending and receiving packets with Scapy

We have already created some packets in the previous recipe. Now we can send and receive those packets with Scapy.

How to do it...

Following are the methods to send and receive packets with scapy module:

  1. Make sure to import the required modules:
from scapy.all import *
from pprint import pprint 
  1. We can use the send() function to send packets at layer 3. In this case, Scapy will handle the routing and layer 2 within it:
network = IP(dst = '192.168.1.1')
transport = ICMP()
packet = network/transport
send(IP(packet)  

This will send an ICMP packet

  1. To send a packet with custom layer 2, we have to use the sendp() method. Here we have to pass the interface to be used for sending...
