A note about containers

Mythic and containers

Mythic uses docker containers to logically separate different components and functions. There are three main categories:

  1. Mythic's main core. This consists of three docker containers stood up with docker-compose:

    1. mythic_server - An async python3 Sanic instance

    2. mythic_postgres - An instance of a postgresql database

    3. mythic_rabbitmq - An instance of a rabbitmq container for message passing between containers

  2. Command and Control (C2) Profiles

    1. Any folder in Mythic/C2_Profiles will be treated like a docker container specific to C2 profiles (more on this in the C2 section).

  3. Payload Types

    1. Any folder in Mythic/Payload_Types will be treated like a docker container specific to a payload type (such as apfell, atlas, etc)

To stop a specific C2 Profile's container, run sudo ./stop_c2_profiles.sh {c2_profile_name} or sudo ./stop_c2_profiles.sh to stop all of them.

To stop a specific Payload Type's container, run sudo ./stop_payload_types.sh {payload_type_name} or sudo ./stop_payload_types.sh to stop all of them.

If you want to reset all of the data in the database, use sudo ./reset_database.sh. Similar to if you want to clear out certain aspects of other containers, there will be a corresponding reset script.

If you want to start/restart any specific payload type container, you can do sudo ./start_payload_types.sh {payload_type_name} and just that container will start/restart. If you want to start multiple, just do spaces between them: sudo ./start_payload_types.sh {payload type 1} {payload type 2}. If you want to get fancy and start all except one, you can do sudo ./start_payload_types.sh -e {payload type 1} -e {payload_type 2} etc.

Mythic shares the networking with the host it's on. This allows Mythic to not worry about exposing specific ports ahead of time for each container since they can be dynamically set by users. However, this does mean that Mythic needs to run as root if any ports under 1024 need to be used.

Architecture

Mythic's architecture is broken out in the following diagram:

Operators connect via a browser to the main Mythic server. This server is a Sanic, python3 web server. This main Mythic server connects to a PostgreSQL database where information about the operations lives. Each of these are in their own docker containers. When Apfell needs to talk to any payload type container or c2 profile container, it does so via RabbitMQ, which is in its own docker container as well.

When an agent calls back, it connects through these c2 profile containers which have the job of transforming whatever the c2 profile specific language/style is back into the normal RESTful API calls that the Mythic server needs.

Mythic Container Locations

The base containers for the Mythic agents are located with the itsafeaturemythic DockerHub repository: https://hub.docker.com/search?q=itsafeaturemythic&type=image.

There are currently base containers for csharp, python3.6, and a special one for poseidon's xgo environment. More containers will be added in the future, but having the base containers pre-configured on DockerHub speeds up install time for operators.
