What it does

Mapping Mitre Attack Techniques is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Maps observed adversary behaviors, security alerts, and detection rules to MITRE ATT&CK techniques and sub-techniques to quantify detection coverage and guide control prioritization. Use when building an ATT&CK-based coverage heatmap, tagging SIEM alerts with technique IDs, aligning security controls to adversary playbooks, or reporting threat exposure to executives. Activates for requests involving ATT&CK Navigator, Sigma rules, MITRE D3FEND, or coverage gap analysis.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/api-reference.md` and `scripts/agent.py`).

It sits in Security, covering Test coverage, Security operations and Prioritization frameworks. It works with Python. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.

When your agent uses it

  • Building an ATT&CK-based coverage heatmap
  • Tagging SIEM alerts with technique IDs
  • Aligning security controls to adversary playbooks
  • Reporting threat exposure to executives

Example prompts

  • “/mapping-mitre-attack-techniques”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Obtain Current ATT&CK Data
  2. Map Existing Detections to Techniques
  3. Prioritize Coverage Gaps Using Threat Intelligence
  4. Build Navigator Heatmap
  5. Generate Executive Coverage Report

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • curl
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • raw.githubusercontent.com

    Also links to:

    • mitre-attack.github.io
    • attack.mitre.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mapping Mitre Attack Techniques loads about 1.8k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 126 tokens; SKILL.md has 584 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~126
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Mapping MITRE ATT&CK Techniques

When to Use

Use this skill when:

  • Generating an ATT&CK coverage heatmap to show which techniques your detection stack addresses
  • Tagging existing SIEM use cases or Sigma rules with ATT&CK technique IDs for structured reporting
  • Aligning your security program roadmap to specific adversary groups known to target your sector

Do not use this skill for real-time incident triage — ATT&CK mapping is an analytical activity best performed post-detection or during threat hunting planning.

Prerequisites

Workflow

Step 1: Obtain Current ATT&CK Data

Download the latest ATT&CK STIX bundle for the relevant matrix (Enterprise, Mobile, ICS):

bash
curl -o enterprise-attack.json \
  https://raw.githubusercontent.com/mitre/cti/master/enterprise-attack/enterprise-attack.json

Use the mitreattack-python library to query techniques programmatically:

python
from mitreattack.stix20 import MitreAttackData

mitre = MitreAttackData("enterprise-attack.json")
techniques = mitre.get_techniques(remove_revoked_deprecated=True)
for t in techniques[:5]:
    print(t["external_references"][0]["external_id"], t["name"])
Step 2: Map Existing Detections to Techniques

For each SIEM rule or Sigma file, assign ATT&CK technique IDs. Sigma rules support native ATT&CK tagging:

yaml
tags:
  - attack.execution
  - attack.t1059.001  # PowerShell
  - attack.t1059.003  # Windows Command Shell

Create a coverage matrix: list each technique ID and mark as: Detected (alert fires), Logged (data present but no alert), Blind (no data source).

Step 3: Prioritize Coverage Gaps Using Threat Intelligence

Cross-reference coverage gaps with adversary groups targeting your sector. Use ATT&CK Groups data:

python
groups = mitre.get_groups()
apt29 = mitre.get_object_by_attack_id("G0016", "groups")
apt29_techniques = mitre.get_techniques_used_by_group(apt29)
for t in apt29_techniques:
    print(t["object"]["external_references"][0]["external_id"])

Prioritize adding detection for techniques used by high-priority threat groups where your coverage is blind.

Step 4: Build Navigator Heatmap

Export coverage scores as ATT&CK Navigator JSON layer:

python
import json

layer = {
    "name": "SOC Detection Coverage Q1 2025",
    "versions": {"attack": "14", "navigator": "4.9", "layer": "4.5"},
    "domain": "enterprise-attack",
    "techniques": [
        {"techniqueID": "T1059.001", "score": 100, "comment": "Splunk rule: PS_Encoded_Command"},
        {"techniqueID": "T1071.001", "score": 50, "comment": "Logged only, no alert"},
        {"techniqueID": "T1055", "score": 0, "comment": "No coverage — blind spot"}
    ],
    "gradient": {"colors": ["#ff6666", "#ffe766", "#8ec843"], "minValue": 0, "maxValue": 100}
}
with open("coverage_layer.json", "w") as f:
    json.dump(layer, f)

Import layer into ATT&CK Navigator (https://mitre-attack.github.io/attack-navigator/) for visualization.

Step 5: Generate Executive Coverage Report

Summarize coverage by tactic category (Initial Access, Execution, Persistence, etc.) with counts and percentages. Provide a risk-ranked list of top 10 blind-spot techniques based on adversary group usage frequency. Recommend data source additions (e.g., "Enable PowerShell Script Block Logging to address 12 Execution sub-technique gaps").

Key Concepts

TermDefinition
ATT&CK TechniqueSpecific adversary method identified by T-number (e.g., T1059 = Command and Scripting Interpreter)
Sub-techniqueMore granular variant of a technique (e.g., T1059.001 = PowerShell, T1059.003 = Windows Command Shell)
TacticAdversary goal category in ATT&CK: Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, Lateral Movement, Collection, C&C, Exfiltration, Impact
Data SourceATT&CK v10+ component identifying telemetry required to detect a technique (e.g., Process Creation, Network Traffic)
Coverage ScoreNumeric (0–100) representing detection completeness for a technique: 0=blind, 50=logged only, 100=alerted
MITRE D3FENDDefensive countermeasure ontology complementing ATT&CK — maps defensive techniques to attack techniques they mitigate

Tools & Systems

  • ATT&CK Navigator: Browser-based heatmap visualization tool for layering coverage scores and annotations on the ATT&CK matrix
  • mitreattack-python: Official MITRE Python library for programmatic access to ATT&CK STIX data (techniques, groups, software, mitigations)
  • Atomic Red Team: MITRE-aligned test library providing atomic test cases to validate detection for each technique
  • Sigma: Detection rule format with ATT&CK tagging support; translatable to Splunk, Sentinel, QRadar, Elastic
  • ATT&CK Workbench: Self-hosted ATT&CK knowledge base for organizations maintaining custom technique extensions

Common Pitfalls

  • Over-claiming coverage: Logging a data source (e.g., process creation events) does not mean the associated technique is detected — a rule must actually fire on malicious patterns.
  • Mapping at tactic level only: Tagging a rule as "attack.execution" without a specific technique ID prevents granular gap analysis.
  • Ignoring sub-techniques: Many adversaries use specific sub-techniques. Coverage of T1059 (parent) doesn't imply coverage of T1059.005 (Visual Basic).
  • Static mapping without updates: ATT&CK releases major versions annually. Coverage maps go stale as techniques are added, revised, or deprecated.
  • Not mapping to adversary groups: Generic coverage maps don't distinguish between techniques used by APTs targeting your sector vs. commodity malware.
