IGMPv3 tunnel

This project implements an IGMPv3 covert channel, a collaborative effort by Marijn, Sam, and Isaac during the "Offensive Technologies" course at the University of Amsterdam.

This project leverages the Source Addresses field within IGMPv3 Membership Query packets (type 0x11) to encapsulate and transmit IP packets. This technique offers a potential method for concealing data transmission within network traffic.

Getting started

Installation

  1. Clone the repository
  2. Install requirements using pip3 -r requirements.txt

Supported operating systems

This application is currently only supported on Linux devices.

Example usage

Run with --help for help.

On device 1

python3 tunnel.py -i <interface> -a <private ip (10.8.0.1)> -p <peer ip (192.168.0.2)>

On device 2

python3 tunnel.py -i <interface> -a <private ip (e.g. 10.8.0.2)> -p <peer ip (e.g. 192.168.0.1)>

Testing

Traffic that uses the private IPs will now be encapsulated into an IGMPv3 packet and sent over the specified interface. On device 1, pinging is now:

$ ping 10.8.0.2

Any IP traffic is encapsulated and thus not limited to a specific protocol (TCP/UDP/etc)
