Invoke-Stealth

Invoke-Stealth is a Simple & Powerful PowerShell Script Obfuscator.

This tool helps you to automate the obfuscation process of any script written in PowerShell with different techniques. You can use any of them separately, together or all of them sequentially with ease, from Windows or Linux.

Requirements

  • Powershell 4.0 or higher
  • Python 3*

*Required to use all features

Download

It is recommended to clone the complete repository or download the zip file. You can do this by running the following command:

git clone https://github.com/JoelGMSec/Invoke-Stealth.git

You can also download the limited version as follows:

powershell iwr -useb https://darkbyte.net/invoke-stealth.php -outfile Invoke-Stealth.ps1

Usage

.\Invoke-Stealth.ps1 -help

Info:  This tool helps you to automate the obfuscation process of
       any script written in PowerShell with different techniques

Usage: .\Invoke-Stealth.ps1 script.ps1 -technique Chimera
         - You can use as single or separated by commas -

Techniques:
       · Chameleon: Substitute strings and concatenate variables
       · BetterXencrypt: Compresses and encrypts with random iterations
       · PyFuscation: Obfuscate functions, variables and parameters
       · ReverseB64: Encode with base64 and reverse it to avoid detections
       · PSObfuscation: Convert content to bytes and encode with Gzip
       · All: Sequentially executes all techniques described above

Warning: The output script will exponentially multiply the original size
         Chameleon & PyFuscation need Python3 to work properly
