att&ck

att&ck is a skill for Claude Code from 0dayInc/pwn. It costs 16 tokens per session (701 once invoked), scanned A, original, MIT.

A testing workflow for MITRE ATT&CK techniques, which are documented patterns of real-world cyberattacks. It covers techniques, sub-techniques, and tactics across supported platforms.

In plain words
What is it for?
Use it to test a named ATT&CK technique or tactic, run red- or purple-team exercises, check coverage, and map procedures to CAPEC attack patterns or CWE weaknesses.
Why use it?
It gives security teams a structured way to emulate attacker behaviour and connect observed weaknesses or detections to standard ATT&CK identifiers.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

att&ck 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 8d 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.

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.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ATT&CK exhaustive testing

Use when the ask names a technique (T1059, T1059.001), a tactic (TA0002), ATT&CK coverage, purple-team emulation, or "test this like an adversary". Pair with capec (how the attack is performed) and cwe (weakness proved).

When to use

  • "T1190", "OS Credential Dumping", "coverage of persistence"
  • Red / purple team playbooks keyed to ATT&CK
  • Mapping detections to techniques

Methodologies

Catalog Role
ATT&CK 19.2 techniques, sub-techniques, tactics (Enterprise / Mobile / ICS)
CAPEC (bundled capec skill) attack-pattern execution for mapped IDs
CWE (bundled cwe skill) weakness IDs after the procedure succeeds
NIST SP 800-115 technical assessment wrapper

How to look up a technique

Each ATT&CK ID is a file in this skill:

references/<id>.md

Examples: references/T1059.md, references/T1059.001.md, references/TA0006.md. Open the file and follow it end-to-end. references/INDEX.md lists every ID.

Exhaustive catalog procedure

  1. Identify platforms in scope (Windows, Linux, SaaS, ICS, Android, …).
  2. Pick tactics in scope (or the whole matrix).
  3. For every applicable technique, run references/<id>.md.
  4. When sub-techniques exist, the parent is incomplete until every child is done.
  5. Record N/A with a reason when the platform does not exist.
  6. Findings cite the technique ID, not only the tactic.
  7. Re-read saved evidence before calling the technique tested.

Tooling

  • Always: skills_recall this skill, then read the technique file.
  • Then: capec and cwe for mapped IDs.
  • Host: pwn_eval, shell, PWN::Plugins::PS.
  • HTTP: PWN::Plugins::BurpSuite / TransparentBrowser.
  • Network: PWN::Plugins::Packet.

Pitfalls

  • Tactics are groupings; they are not techniques.
  • Atomic Tests / scanner mappings are inventory until you execute and save evidence.
  • Skipping sub-techniques is not parent coverage.
  • Detection engineering without an emulation attempt is not a test.

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.

att&ck is a skill published in the GitHub repository 0dayInc/pwn (78 stars, last pushed 4d ago), licensed MIT. It adds 16 tokens to every session and 701 once invoked, about $0.0001 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 2026-08-30.
