Conquest is a feature-rich, extensible and malleable command & control/post-exploitation framework developed for penetration testing and adversary simulation. Conquest's team server, operator client and agent have all been developed from scratch using the Nim programming language and are designed with modularity and flexibility in mind. It features custom C2 communication via binary packets over HTTP, a client GUI developed using Dear ImGui and the Monarch agent, a modular C2 implant aimed at Windows targets.

Caution

Conquest is designed to be only used for educational purposes, research and authorized security testing of systems that you own or have an explicit permission to attack. The author provides no warranty and accepts no liability for misuse.

Getting Started

The Conquest team server and operator client are meant to be compiled and used on a UNIX operating system.

1. Install Nim

curl https://nim-lang.org/choosenim/init.sh -sSf | sh

2. Build the Conquest team server and client. When first used, these commands download all required dependencies and libraries.

nimble server
nimble client

3. Start the team server with a C2 profile.

bin/server -p data/profile.toml

4. Start the operator client and connect it to a team server

bin/client [-i <address> (default: localhost)] [-p <port> (default: 37573)]
