mythic

mythic is a skill for Claude Code from MingyiSecLab/Mingyi-Atlas. It costs 90 tokens per session (1,737 once invoked), scanned B, original, Apache-2.0.

A guide to operating Mythic, a container-based command-and-control system that can run different remote agents through a web interface.

In plain words
What is it for?
Use it to install Mythic, add Windows, macOS, Linux or cross-platform agents, configure communication profiles and send tasks through its scriptable interface.
Why use it?
It gives security teams one place to manage agents for different operating systems and automate tasking during an authorised exercise.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

mythic scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

Mythic C2 Operator Skill

Mythic (cody-thomas/Mythic) is a containerized, multi-agent C2 framework. Strengths: pluggable agents (~10+ official), good for cross-platform engagements, JSON-RPC tasking model is scriptable.

Setup (one-time, on the operator server)

# Clone + install
git clone https://github.com/its-a-feature/Mythic
cd Mythic
sudo ./install_docker_ubuntu.sh        # or install_docker_kali, install_docker_macos
sudo ./mythic-cli start
# Web UI: https://<host>:7443
# Default creds: mythic_admin / printed during install

# Install agents (each is a separate container)
sudo ./mythic-cli install github https://github.com/MythicAgents/Apollo     # Windows .NET agent
sudo ./mythic-cli install github https://github.com/MythicAgents/Poseidon   # macOS/Linux Go agent
sudo ./mythic-cli install github https://github.com/MythicAgents/Medusa     # cross-platform Python
sudo ./mythic-cli install github https://github.com/MythicAgents/Athena     # cross-platform .NET 6

Agent matrix

Agent Platform Lang Best for
Apollo Windows C# / .NET Framework 3.5+ Windows-heavy engagements, .NET interop
Poseidon macOS, Linux Go Cross-platform, single static binary
Athena Windows / macOS / Linux .NET 6/7/8 Modern .NET, AOT-compiled
Apfell macOS JavaScript for Automation (JXA) Native macOS execution via osascript
Medusa any Python Quick prototypes, fileless
Service Wrapper Windows C++ Persistence via Windows service

Profile matrix

Profiles = the comms channel. An agent can use one or more profiles.

Profile Transport Detection
http Plain HTTP(S) with configurable headers, paths, jitter, sleep Easiest to fingerprint; use behind redirector + domain fronting
websocket WS / WSS Long-lived; suspicious from desktop
smb Named pipe over SMB Peer-to-peer between Apollo agents — no internet needed for inner workstations
dns DNS TXT / A queries to attacker NS Slow, but bypasses every HTTP-only firewall
peer-to-peer (SMB) One agent forwards another's traffic Use for deep network — only one egress point needed

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
