What?

Moonshine is a C2 framework with a custom Lua interpreter (called Moon, see here for further details) runtime at it's core. The runtime is used in the implants to execute scripts on the remote host, with the option of loading Lua C or script modules to provide additional functionality. The communication channels for both implant and server are implemented as Lua scripts, allowing for complete control and flexibility.

The goals for the framework are:

• To allow for rapid prototyping of new adversarial techniques.
• To allow for simulation of adversarial techniques.
• To have an implant that is easily expandable and customisable, with a minimal core.
• To have an implant that works cross-platform.
• To have a server that can be accessed via a REST based API, so the framework can easily be automated or integrated with other tools.

Use?

Build

A Makefile is also included that not only provides a convenience wrapper around CMake, but also for Docker which enables the framework to be cross-compiled within a container containing all the pre-requisite development tools. The Makefile implements the following common targets:

$ make (debug*|release|install|dist|check|clean|distclean)

* default target if no arguments are supplied.

For example to compile the framework using native development tools already installed on the host, execute:

make install

The resultant build artifacts can then be found within the _install subdirectory.

The project also includes a test harness. To execute, use the standard CMake commands or use the provided Makefile (make check).

To use within another CMake based project, simply include using the method of choice for the project e.g. 'add_subdirectory', 'ExternalProject', 'FetchContent', 'CPM'.

Building using a Docker container

The Makefile wrapper can also be used to initiate cross-compilation to both the Linux and Windows platforms using a Docker container that has the required development tools pre-installed:

cd <moon directory>
make TARGET=linux install

-or-

make TARGET=mingw install

Unfortunately due to the requirement of being able to execute compiled binaries during the build process, cross-compiling the framework to target the macOS platform is not possible within a Docker container.

Native build instructions

To build, at a minimum you'll need to install the CMake build system and version 14 of the Clang compiler. All dependant libraries are automatically downloaded and compiled by the build system. Where possible, libraries are statically linked into the resultant artifacts at compile time rather than requiring libraries to be available on the local system during runtime.

Windows

For a less arduous setup, use choco. Alternatively, see the "Cross-compiling" section below.

Set-ExecutionPolicy Bypass -Scope Process -Force;
[Net.ServicePointManager]::SecurityProtocol = "tls12"  # Only needed on Windows < 10

cd <moon directory>
make install

Build artifacts can be found within the _install subdirectory.

macOS

xcode-select --install

For a less arduous setup, use Homebrew.

brew install cmake

cd <moon directory>
make install

Build artifacts can be found within the _install subdirectory.

Linux

Download a recent version of cmake from here or install via the Kitware APT Repository, and make sure that the cmake binary is accessible via the $PATH.

sudo apt-get install build-essential wget
wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh 14

cd <moon directory>
make install

Build artifacts can be found within the _install subdirectory.

First, the server component will need to be executed. The server provides a REST API and also a WebSocket interface for clients (i.e. operators) to interact with the server. The REST API will allow an operator to create listeners, generate implants artifacts, and send tasks to connected implants.

The server publishes a Swagger / OpenAPI based interface that provides details of the REST API in both a human-readable format (website), and also as a json descriptor file for tools to consume. As such, in conjunction with a tool such as the openapi-generator, SDK client libraries can be easily generated for many programming languages. See the examples/client-sdk/python subdirectory for a Python SDK that has been generated using an openapi generator.

A Jupyter Notebook named api.ipynb can also be found within the examples repositor. This uses the generated Python SDK and provides example usage of the framework.

Lua modules and scripts for use in the framework can also be found in examples/scripts.
