Command and Control (C2) Server & Client Project

Introduction

This project aims to better my understanding of Command and Control (C2) servers and expand my defensive skills against such threats. The project includes a C2 server and client written in Python, demonstrating basic interactions between a server and multiple clients.

Requirements

• Python 3.x
• Python packages:
  • cryptography
  • requests
• AWS account for deployment (Free Tier)

Setup

AWS Environment

1. Create an EC2 instance on AWS. (Free tier eligible) (Ubuntu Server 22.04 LTS)
2. Configure security groups to allow traffic on the desired port (9999).
   • Add a custom inbound TCP rule to allow traffic on port 9999.
   • Optionally-SortOfNotOptionally, allow traffic on port 80 for HTTP.

Development Environment

1. Clone the repository:

   git clone https://github.com/cwsecur1ty/C2-Server.git
   cd C2-Server-Project

2. Install required Python packages:

   pip install cryptography requests

3. Configure the server:
   • Update Config/config.json with any needed changes (usually none).
