map-malware-behavior

map-malware-behavior is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 50 tokens per session (329 once invoked), scanned A, original, Apache-2.0.

A method for linking observed malicious actions to MITRE ATT&CK, a public framework that names and organizes common attacker techniques.

In plain words
What is it for?
It is for recording observations, selecting supported ATT&CK techniques, documenting the evidence for each match, and guiding detection or response work.
Why use it?
It gives investigations and reports a consistent behavior map without claiming an attacker or malware family that the evidence does not prove.

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 A, and why

map-malware-behavior scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Map Malware Behavior

Overview

Translate evidence into current ATT&CK technique references while keeping the original observation primary. Map only behaviors supported by evidence and preserve platform/version context.

Read references/behavior-mapping.md for evidence and mapping fields.

Workflow

  1. Normalize observations.
    • Record actor/process, action, object, time, environment, privilege, source, and confidence.
  2. Open current ATT&CK content.
    • Select the relevant Enterprise, Mobile, ICS, cloud, container, or platform matrix and record the version/date checked.
  3. Match behavior, not keywords.
    • Read the technique definition and platform applicability.
    • Choose the most specific supported sub-technique; preserve multiple plausible mappings as alternatives when evidence is incomplete.
  4. Record mapping evidence.
    • Link each technique to the exact observation and explain why it fits and where it does not.
  5. Avoid attribution inflation.
    • Do not infer actor, malware family, campaign, intent, or sequence solely because ATT&CK pages list similar procedure examples.
  6. Use the map.
    • Route to containment, hunting, or detection content and name telemetry gaps.

Output

Return an evidence-to-technique table, platform and ATT&CK version/date, confidence, alternative mappings, telemetry gaps, and defensive use.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

map-malware-behavior is a skill published in the GitHub repository gaelic-ghost/socket (7 stars, last pushed 9d ago), licensed Apache-2.0. It adds 50 tokens to every session and 329 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
