What it does

Analyzing Threat Actor Ttps With Mitre Navigator is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Map advanced persistent threat (APT) group TTPs to the MITRE ATT&CK framework using the attackcti Python library to query STIX/TAXII data for group-technique associations, then generate ATT&CK Navigator layer files to visualize and compare defensive coverage against adversary profiles. Use when profiling an APT group's techniques, building Navigator coverage heatmaps, or assessing technique coverage gaps against a specific threat actor.

Its SKILL.md is about 670 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. 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

  • Profiling an APT groups techniques
  • Building Navigator coverage heatmaps
  • Assessing technique coverage gaps against a specific threat actor

Example prompts

  • “/analyzing-threat-actor-ttps-with-mitre-navigator”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Query ATT&CK STIX data for target threat group using attackcti
  2. Extract techniques associated with the group via STIX relationships
  3. Generate ATT&CK Navigator layer JSON with technique annotations
  4. Overlay detection coverage to identify gaps
  5. Export layer for team review and defensive planning

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.

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

  • Network

    No URLs in SKILL.md.

    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

Analyzing Threat Actor Ttps With Mitre Navigator loads about 667 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 122 tokens; SKILL.md has 177 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~122
When it runs · the whole SKILL.md, loaded when a task matches
~667
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

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.

Analyzing Threat Actor TTPs with MITRE Navigator

Overview

The MITRE ATT&CK Navigator is a web application for annotating and visualizing ATT&CK matrices. Combined with the attackcti Python library (which queries ATT&CK STIX data via TAXII), analysts can programmatically generate Navigator layer files mapping specific threat group TTPs, compare multiple groups, and assess detection coverage gaps against known adversaries.

When to Use

  • When investigating security incidents that require analyzing threat actor ttps with mitre navigator
  • When building detection rules or threat hunting queries for this domain
  • When SOC analysts need structured procedures for this analysis type
  • When validating security monitoring coverage for related attack techniques

Prerequisites

  • Python 3.8+ with attackcti and stix2 libraries installed
  • MITRE ATT&CK Navigator (web UI or local instance)
  • Understanding of STIX 2.1 objects and relationships

Steps

  1. Query ATT&CK STIX data for target threat group using attackcti
  2. Extract techniques associated with the group via STIX relationships
  3. Generate ATT&CK Navigator layer JSON with technique annotations
  4. Overlay detection coverage to identify gaps
  5. Export layer for team review and defensive planning
