mythic-c2-readonly skillA
mythic-c2-readonly is agent-read markdown (skill) from dreadnode/capabilities: Use when reviewing Mythic C2 operation data in read-only mode — viewing callbacks, task history, credentials, files, artifacts, and other collected data..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add dreadnode/capabilities/mythic-c2-readonly@git:20260504.2a64374mdr add dreadnode/capabilities/mythic-c2-readonly@sha256:da1440769d8bc6bdPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
