Co is a .NET command and control framework that aims to highlight the attack surface of .NET, make the use of offensive .NET tradecraft easier, and serve as a collaborati and control platform for red teamers.

Co is an ASP.NET Core, cross-platform application that includes a web-based interface that allows for multi-user collaboration.

Quick-Start Guide

Please see the Installation and Startup guide to get started with Co!

The Wiki documents most of Co's core features and how to use them.

Features

Co has several key features that make it useful and differentiate it from other command and control frameworks:

* Intuiti - Co provides an intuitive web application to easily run a collaborative red team operation.
* Multi-Platform - Co targets .NET Core, which is multi-platform. This allows Co to run natively on Linux, MacOS, and Windows platforms. Additionally, Co has docker support, allowing it to run within a container on any system that has docker installed.
* Multi-User - Co supports multi-user collaboration. The ability to collaborate has become crucial for effective red team operations. Many users can interact with the same Co server and operate independently or collaboratively.
* API Driven - Co is driven by an API that enables multi-user collaboration and is easily extendible. Additionally, Co includes a Swagger UI that makes de and debugging easier and more con.
* Listener Profiles - Co supports listener “profiles” that control how the network communication between Grunt implants and Co listeners look on the wire.
* Encrypted Key Exchange - Co implements an encrypted key exchange between Grunt implants and Co listeners that is largely based on a similar exchange in the Empire project, in addition to optional SSL encryption. This achieves the cryptographic property of forward secrecy between Grunt implants.
* Dynamic Compilation - Co uses the Roslyn API for dynamic C# compilation. Every time a new Grunt is generated or a new task is assigned, the relevant code is recompiled and obfuscated with ConfuserEx, a totally static payloads. Co reuses much of the compilation code from the SharpGen project, which I described in much more detail in a previous post.
* Inline C# Execution - Co borrows code and ideas from both the SharpGen and SharpShell projects to allow operators to execute C# one-liners on Grunt implants. This allows for similar functionality to that described in the SharpShell post, but allows the one-liners to be executed on remote implants.
* Tracking Indicators - Co tracks “indicators” throughout an operation, and summarizes them in the Indicators menu. This allows an operator to conduct actions that are tracked throughout an operation and easily summarize those actions to the blue team during or at the end of an assessment for deconfliction and educational purposes. This feature is still in it’s infancy and still has room for impro.
* De in C# - Personally, I enjoy de in C#, which may not be a surprise for anyone that has read my latest blogs or tools. Not e might agree that de in C# is ideal, but hopefully e agrees that it is nice to have all components of the framework written in the same language. I’ it very con to write the server, client, and implant all in the same language. This may not be a true “feature”, but hopefully it allows others to contribute to the project fairly easily.
