Poseidon Logo

Poseidon is a Golang agent that compiles into Linux and macOS x64 executables. It leverages the karalabe/xgo project to cross compile with CGO for both of these operating systems. This Poseidon instance supports Mythic 2.3 and will be updated as necessary. It does not support Mythic 2.2 and lower.

The agent has mythic_payloadtype_container==0.1.8 PyPi package installed and reports to Mythic as version "12".

How to install an agent in this format within Mythic

When it's time for you to test out your install or for another user to install your agent, it's pretty simple. Within Mythic you can run the mythic-cli binary to install this in one of three ways:

  • sudo ./mythic-cli install github https://github.com/user/repo to install the main branch
  • sudo ./mythic-cli install github https://github.com/user/repo branchname to install a specific branch of that repo
  • sudo ./mythic-cli install folder /path/to/local/folder/cloned/from/github to install from an already cloned down version of an agent repo

Now, you might be wondering when should you or a user do this to properly add your agent to their Mythic instance. There's no wrong answer here, just depends on your preference. The three options are:

  • Mythic is already up and going, then you can run the install script and just direct that agent's containers to start (i.e. sudo ./mythic-cli payload start agentName and if that agent has its own special C2 containers, you'll need to start them too via sudo ./mythic-cli c2 start c2profileName).
  • Mythic is already up and going, but you want to minimize your steps, you can just install the agent and run sudo ./mythic-cli mythic start. That script will first stop all of your containers, then start everything back up again. This will also bring in the new agent you just installed.
  • Mythic isn't running, you can install the script and just run sudo ./mythic-cli mythic start.

Documentation

The Poseidon documentation source code can be found in the documenation-payload/poseidon directory. View the rendered documentation by clicking on Docs -> Agent Documentation in the upper right-hand corner of the Mythic interface.

Building Outside of Mythic

If you want to build outside of Mythic, you can use the Makefile included in the project's agent_code directory. You will need to modify the variables at the top of the Makefile to match the C2 profile information you want to build into your agent. To get all the pieces you need (like UUID and AES key), you need to build the agent within Mythic (or at least kick off an unsuccessful build), then copy that information. To find the information you need, simply go to the Payloads page and click the blue info icon. You'll see the UUID, encryption key, and any other information you need for building to put into your Makefile.
