Elite - Elite is the client-side component of the Covenant

项目说明

Deprecated (Temporarily)

The parent Co project no longer requires a client-side application. Elite has temporarily been deprecated. Please instead use the web interface included with the Co project.

Elite may e be brought up-to-date with the Co project as an alternati, but for now this project is not updated and will not work with Co v0.3 or higher.

Elite

Elite is a .NET core, client application built for interacting with Co.

Co

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 robust API to enable a client-ser that allows for multi-user collaboration. There are three main components of Co's architecture:

* Co - Co is the ser component of the client-ser. Co runs the command and control ser on infrastructure shared between operators. I will also frequently use the term "Co" to refer to the entire o project that includes all components of the architecture.
* Elite - Elite is the client-side component of the client-ser. Elite is a command-line interface that operators use to interact with the Co server to conduct operations.
* Grunt - A "Grunt" is the name of Co's implant that is deployed to targets.

Features

Co has several key features:

* Multi-Platform - Co and Elite both target .NET Core, which makes them multi-platform. This allows these programs to run natively on Linux, MacOS, and Windows platforms. Additionally, both Co and Elite ha support, allowing these programs 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 start Elite clients that connect to the same Co server and operate independently or collaboratively.
* API Driven - Co is driven by a ser 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.

Users Quick-Start Guide

First, you need to start Co! Go checkout the Co README to see how to do that.

Dotnet Core

The easiest way to use Elite, is by installing dotnet core. You can download dotnet core for your platform from here.

Once you ha dotnet core, we can build and run Elite using the dotnet CLI:

Docker

Elite can also be run with Docker. There are a couple of gotchas with Docker, so I only recommend using docker if you are familiar with docker or are willing to learn the subtle gotchas.

First, build the docker image:

Now we can run Elite in a Docker container:

The --username AdminUser and --computername <Co IP> are arguments being passed to Elite. This instructs Elite to connect to a Co instance hosted at the specifiec IP address and login as a user named AdminUser.

The -it parameter is a Docker parameter that indicates that we should begin Elite in an interactive tty. This is important, as Elite is an interacti application! The -/path/to/Elite/Data:/app/Data parameter mounts a shared Data folder between your host and container, and allows you to easily copy/paste outside tools and payloads generated during operation with Elite. Be sure to replace /absolute/path/to/Elite/Data with the location of your own Elite Data folder.

You will also be prompted to provide a password for the AdminUser user. Alternatively, you can set this non-interactively with the --password parameter to Elite, but this will leave your password in plaintext in command history, not ideal.
