TL;DR: We created new Mythic extensions to simplify container-centric assessments, including Kubernetes and Docker-based ceded access workflows. These tools help operators wrap Mythic payloads in OCI-compatible containers and publish them to a self-hosted registry. Check the container_wrapper and container_registry on GitHub.

Introduction

There are quite a few command and control (C2) frameworks available for teams to use, but most are designed around Windows-heavy environments. As Kubernetes has become more common for orchestrating across Linux servers, we wanted to ease some workflows around penetration engagements that are utilizing container technology (i.e., container-centric). Fortunately, Mythic C2’s modular design gives us a flexible foundation to build on. In this post, we’ll highlight two new building blocks that help operators package and deliver Mythic payloads in container-centric environments.

Why C2 Initial Access?

In adversary simulation engagements, clients often want to cede access in a way that reflects realistic execution paths. For Kubernetes environments, that may mean running a C2 payload inside a container instead of using a traditional dropbox-style test. Until now, our process for bundling a Mythic payload into a container and pushing it to a registry was mostly manual. So these two minimum viable product (MVP) extensions were created for Mythic to help abstract that manual process, leveraging open standards from the container ecosystem, into a few button presses in the web UI.

To clarify, we are not releasing any new tactics, …
