Python Network Hacking with Kali Linux and Scapy = attack one! 😀

Introduction

This tutorial provides a step-by-step guide on using Python and Scapy for network hacking with Kali Linux. It emphasizes the importance of understanding network protocols and how misconfigurations can lead to vulnerabilities. By combining Python scripting with network knowledge, you can gain powerful insights into network security.

Step 1: Set Up Your Environment

• Install Kali Linux: Ensure you have Kali Linux installed on your machine. You can download it from the official Kali website.
• Install Scapy: Scapy is a powerful Python library used for packet manipulation. You can install it using the following command in your terminal:

  sudo apt-get install python3-scapy
  

• Use Sudo for Elevated Privileges: Many networking tasks require root privileges. Always start your scripts with sudo.

Step 2: Understand Network Topology

• Familiarize Yourself with Network Layout: Before proceeding, understand the basic network topology you will be working with.
• Identify Key Components: Focus on elements like switches, routers, and endpoints that will be involved in your testing and attacks.

Step 3: Capture Network Frames

• Use Scapy to Capture Frames: Utilize Scapy to listen to network traffic.

  from scapy.all import sniff
  sniff(prn=lambda x: x.show(), count=10)
  

• Analyze Captured Frames: Once you've captured frames, inspect them to understand the data flowing through your network.

Step 4: Create a Scapy Script for Spanning Tree Protocol

• Write a Script to Manipulate STP: Create a script that will interact with the Spanning Tree Protocol (STP) to block paths to the root switch.

  from scapy.all import *
  
  def send_bpdu():
      bpdu = Ether()/STP()
      sendp(bpdu, iface='eth0')
  

• Test Your Script: Run the script and monitor its effects on the network topology to ensure it behaves as expected.

Step 5: Conduct a Network Test Before Attack

• Test Network Stability: Before executing any attacks, run tests to confirm the current state of the network.
• Use Tools like Wireshark: Capture traffic using Wireshark to visualize the network behavior and confirm STP operations.

Step 6: Execute Your Attack

• Deploy Your STP Script: Once testing is complete, execute your script to manipulate the STP.
• Monitor Network Changes: Use Wireshark to observe how your actions affect the network, specifically how paths are rerouted or blocked.

Step 7: Analyze Results with Wireshark

• Capture Traffic During the Attack: Use Wireshark to capture and analyze the network traffic while your script is running.
• Identify Changes: Look for changes in the network topology and understand how your script impacted the STP.

Conclusion

In this tutorial, you learned how to set up your environment for network hacking using Python and Scapy, as well as how to manipulate the Spanning Tree Protocol. Armed with this knowledge, you can explore further into network security, testing misconfigurations and vulnerabilities. For continued learning, consider diving deeper into coding with Python and exploring more advanced networking concepts.
