Ironsquirrel - Encrypted Exploit Delivery for the Masses - Hacking Land

This project aims at delivering browser exploits to the victim browser in an encrypted fashion. Ellyptic-curve Diffie-Hellman (secp256k1) is used for key agreement and AES is used for encryption.

By delivering the exploit code (and shellcode) to the victim in an encrypted way, the attack can not be replayed. Meanwhile the HTML/JS source is encrypted thus reverse engineering the exploit is significantly harder.

Getting Started
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites
Mandatory dependencies - clone the IRONSQUIRREL project, cd into the project directory, and run the following commands:

sudo apt-get install ruby-dev
 bundle install

Actually nokogiri and gibberish gems will be installed.
Optional dependency (for Powershell based environment aware encrypted payload delivery): Ebowla https://github.com/Genetic-Malware/Ebowla

Installing

Clone the IRONSQUIRREL project
Install the prerequisites
(Optional) Edit IRONSQUIRREL.rb
1. Change the listen port
2. If Ebowla is used, configure the paths
(Optional) If Ebowla is used, configure genetic.config.ecdh in the Ebowla install directory
Run IRONSQUIRREL.rb

ruby IRONSQUIRREL.rb --exploit full_path_to_exploit

Example

ruby IRONSQUIRREL.rb --exploit /home/myawesomeusername/IRONSQUIRREL/exploits/alert.html

After that, visit the webserver from a browser. Example output:
