Bashfuscator: fully configurable and extendable Bash obfuscation framework

Bashfuscator

Bashfuscator is a modular and extendable Bash obfuscation framework written in Python 3. It provides numerous different ways of making Bash one-liners or scripts much more difficult to understand. It accomplishes this by generating convoluted, randomized Bash code that at runtime evaluates to the original input and executes it. It makes generating highly obfuscated Bash commands and scripts easy, both from the command line and as a Python library.

Bashfuscator

The purpose of this project to give Red Team the ability to bypass static detections on a Linux system, and the knowledge and tools to write better Bash obfuscation techniques.

This framework was also developed with Blue Team in mind. With this framework, Blue Team can easily generate thousands of unique obfuscated scripts or commands to help create and test detections of Bash obfuscation.

Payload support

Though Bashfuscator does work on UNIX systems, many of the payloads it generates will not. This is because most UNIX systems use BSD style utilities, and Bashfuscator was built to work with GNU style utilities. In the future BSD payload support may be added, but for now, payloads generated with Bashfuscator should work on GNU Linux systems with Bash 4.0 or newer.

Installation & Requirements

Bashfuscator requires Python 3.6+.

On a Debian-based distro, run this command to install dependencies:

sudo apt-get update && sudo apt-get install python3 python3-pip python3-argcomplete xclip

On an RHEL-based distro, run this command to install dependencies:

sudo dnf update && sudo dnf install python3 python3-pip python3-argcomplete xclip

Then, run these commands to clone and install Bashfuscator:

git clone https://github.com/Bashfuscator/Bashfuscator
cd Bashfuscator
python3 setup.py install --user

Only Debian and RHEL based distros are supported. Bashfuscator has been tested working on some UNIX systems but is not supported on those systems.
