mythic_sync

The mythic_sync utility connects to a Mythic C2 server (>=3.0.0+) to ingest events and post these events to the Ghostwriter (>=v3.0.1) GraphQL API to create real-time activity logs.

This tool automatically logs all new agent callbacks and every operator's Mythic commands, comments, and output into Ghostwriter so operators can focus more on technical execution and less on manual and tedious logging and reporting activities.

The current version of mythic_sync requires Mythic >=v3.0.0 and Ghostwriter >=v3.0.1.

Usage

Getting Started

To authenticate to your instances of Mythic and Ghostwriter, you will need this information handy:

• Ghostwriter URL
• Ghostwriter GraphQL API token
• Ghostwriter log ID
• Mythic credentials

Ghostwriter API Token & Activity Log

You can get your log's ID by opening the log's webpage and looking at the top of the page. You'll see "Oplog ID #" followed by a number. That's the ID number you need.

To generate an API token for your Ghostwriter instance, visit your user profile and click on the "Create" button in the "API Tokens" section.

The token must be attached to an account that has access to the project containing your target oplog. You can read more about the authorization controls on the Ghostwriter wiki.

Execute via Mythic 3.0+ and mythic-cli

For the easiest experience with mythic_sync, install it via the mythic-cli tool. When installed this way, the mythic_sync service will become part of your Mythic deployment. You can then use mythic-cli to manage mythic_sync (just like Mythic) and the service will come up and go down alongside your other Mythic services.

On your Mythic server, run: sudo ./mythic-cli mythic_sync install github https://github.com/GhostManager/mythic_sync

Follow the prompts to configure mythic_sync with your Mythic and Ghostwriter server configuration.

You can get your Ghostwriter Oplog ID by visiting your log in your web browser and looking at the top of the page or the URL. A URL with /oplog/12/entries means your Oplog ID is 12.

sudo ./mythic-cli mythic_sync install github https://github.com/GhostManager/mythic_sync

Please enter your GhostWriter OpLog ID: 12

[+] Successfully installed mythic_sync!
[+] Successfully updated configuration in .env

Execute via Stand Alone Docker

Alternatively, you can use Docker and docker-compose to run the mythic_sync container. Use this option if you'd prefer to run mythic_sync on a different server than your Mythic containers or don't want to use mythic-cli to manage the service.

After cloning repository, open the settings.env file and fill in the variables with appropriate values. The following is an example:

MYTHIC_IP=10.10.1.100
MYTHIC_USERNAME=mythic_admin
MYTHIC_PASSWORD=SuperSecretPassword
GHOSTWRITER_API_KEY=eyJ0eXAiO...
GHOSTWRITER_URL=https://ghostwriter.mydomain.com
GHOSTWRITER_OPLOG_ID=12

Once the environment variables are set up, you can launch the service by using docker-compose:

docker-compose up

Verify Successful Start-Up

Open your Ghostwriter log and look for an initial entry. You should see something like the following:

> Initial entry from mythic_sync at: <server_ip>. If you're seeing this then oplog syncing is working for this C2 server!

If so, you're all set! Otherwise, check the logs from the docker container for error messages. Fetch the logs with:

sudo ./mythic-cli logs mythic_sync

Troubleshooting

Ensure the host where mythic_sync is running has network access to the Ghostwriter and Mythic servers.

mythic_sync uses an internal Redis database to sync what events have already been sent to Ghostwriter, avoiding duplicates.

If the mythic_sync service goes down, it is safe to stand it back up and avoid duplicates as long as nothing has forcefully stopped Mythic's Redis container.
