Backdoor

A backdoor that is able to run on Windows and Linux.

How to install

First you should have downloaded and installed Python 3.7 or a later version.

Download the repository

git clone https://github.com/EiSiMo/Backdoor

Navigate to the folder

cd Backdoor/client_python

or

cd Backdoor/server_python

Install the requirements

pip3 install -r requirements.txt

If you want to know how to compile the client to a binary file check out pyinstaller. Tip: maybe the -w (no popup window) -F (all in one file) flags are interesting for you.

How to use

Client versions

The main version of the client is the Python version but I am currently working on a different one written in Rust because the Python client is very big if compiled (around 60 MiB). The goal is to implement the same functions on both versions so they are compatible with just one server. THE RUST VERSION IS VERY UNSTABLE AND YOU SHOULD NOT USE IT!

Group system

The server uses a group system to control the clients. You can address them with their indices(0, 1, 2, ...) or with the groups, in which they are. When they connect, all clients are automatically in the 'all' group. So for example you can list all connected clients with list -s all. You also can address multiple groups or indices at once for example list -s 1 2 3. If you select one client two times it will be addressed only once: list -s all 1.

Encryption

The backdoor uses 2048 bit RSA to exchange the AES key which the server generates. Every sessions has its own AES key. AES is used in the 256 bit GCM mode.
