mapping-attack-techniques

A router for MITRE ATT&CK, a shared vocabulary for describing attacker behaviours such as credential theft or lateral movement.

In plain words
What is it for?
Use it to resolve technique IDs or names, map threat intelligence to procedures, plan coverage, or run purple-team exercises that test and close detection gaps.
Why use it?
It connects an ATT&CK technique, tactic, threat report, or emulation plan to the relevant security procedure and links testing with detection validation.

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

mapping-attack-techniques scanned grade A 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mapping ATT&CK Techniques

ATT&CK is a shared vocabulary, not a methodology. Its value is that offense, detection, and response can name the same behaviour — which makes this skill a router, not a technique catalogue. It resolves a technique to the skill that holds the actual procedure, and it runs the loop that connects the two sides.

When to Use

  • A request names a technique ID (T1003.001), a technique name ("Kerberoasting"), or a tactic ("we need lateral movement coverage")
  • Converting a threat intel report or an adversary emulation plan into work
  • Planning or reporting coverage against the matrix
  • Running a purple team exercise: emulate, detect, validate, close the gap
  • Choosing which skill applies when a request spans offense and defense

When NOT to Use

  • A plain-language request ("dump creds off this host") — the domain skills trigger directly on that; routing through here adds a hop for nothing
  • Code-level vulnerability work — ATT&CK does not model source defects; use auditing-code-for-vulnerabilities with CWE and ASVS instead
  • AI/LLM systems — use securing-ai-systems; the framework there is MITRE ATLAS, not ATT&CK Enterprise
  • Mobile targetstesting-mobile-applications; the Mobile matrix has its own IDs that do not correspond to Enterprise ones

The Index

secskills-core/ttp-index.json maps techniques to the skills that cover them. Read it directly to resolve a lookup:

# Which skill covers this technique?
python3 -c "
import json;d=json.load(open('secskills-core/ttp-index.json'))
print([r for r in d['techniques'] if r['id']=='T1003.001'])"

# Everything under one tactic
python3 -c "
import json;d=json.load(open('secskills-core/ttp-index.json'))
[print(r['id'], r['name'], '→', ', '.join(r['skills']))
 for r in d['techniques'] if 'TA0008' in r['tactics']]"

# Search by name when you have words, not an ID
rg -i 'kerberoast|pass the hash' secskills-core/ttp-index.json

Each skill also carries a generated ## ATT&CK Coverage section listing its techniques. That section and the index are kept in sync by scripts/sync_attack.py; the index is the source of truth.

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.
