DNS-DataExfiltration

Description

This implementation is inspired by the PyExfil Project (Copyright (c) 2014 Yuval tisf Nativ, Link: https://github.com/ytisf/PyExfil)

In this repository, you will find a Python3 implementation of my Data-Exfiltration approach to bypass Firewalls for e.g. File-Transfers. This piece of code can be used for penetration testing !only! on your own devices!

Just study the code and you will understand the features this implementation provides for you. Most imporant features are:

  • Fast & reliable encryption using SALSA20
  • Integrity Protection / Fail safe transfer by using CRC32
  • Adjustable Packet Size & Sending Interval
  • No malformed DNS requests

Prerequisites

Make sure Python3 is installed on your System.

  1. Clone this repository
git clone https://github.com/cr4kn4x/DNS-DataExfiltration.git
  1. Open the folder of the cloned repository in your shell
cd DNS-DataExfiltration
  1. Initialize Python virtual environment
python python -m venv ./
  1. Activate virtual environment
.\Scripts\Activate.ps1
  1. Install requirements
pip install -r requirements.txt
  1. Run DNS-Exfiltration Server
python Server/main.py
  1. Run DNS-Exfiltration Client
python Client/main.py
