analyzing-threat-actor-ttps-with-mitre-attackMaps threat actor behavior and observed indicators to MITRE ATT&CK, builds Navigator coverage heatmaps, finds detection gaps and produces threat intelligence reports.
Analysts use this skill to connect what a threat actor does to the MITRE ATT&CK framework. It maps observed behavior and IOCs to specific techniques across the Enterprise, Mobile and ICS matrices, builds coverage heatmaps as ATT&CK Navigator layers, identifies gaps in detection, and writes reports that link indicators to adversary techniques.
The workflow queries ATT&CK data programmatically with the attackcti library, then maps a threat actor to its techniques, and uses Navigator layers, which are JSON files annotating techniques with scores, colors and comments, to visualize actor coverage, detection capability or risk. The background section explains tactics, techniques and sub-techniques, and group profiles with aliases, targeted sectors, software and procedure-level detail.
Prerequisites are Python 3.9 or newer with mitreattack-python, attackcti and stix2, the ATT&CK Navigator, familiarity with STIX 2.1 attack patterns, and threat intelligence from reports or MISP or OpenCTI. The folder ships scripts agent.py and process.py, reference notes on APIs, standards and workflows, and a report template.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
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.
Ships 2 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
attack.mitre.orggithub.commitre-attack.github.ioFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
ATT&CK Threat Actor Mapping loads about 2.5k tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 366 words of instructions outside code blocks.
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.
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.

This skill also uses 7 other files; get the full folder from GitHub.MITRE ATT&CK is a globally-accessible knowledge base of adversary tactics, techniques, and procedures (TTPs) based on real-world observations. This skill covers systematically mapping threat actor behavior to the ATT&CK framework, building technique coverage heatmaps using the ATT&CK Navigator, identifying detection gaps, and producing actionable intelligence reports that link observed IOCs to specific adversary techniques across the Enterprise, Mobile, and ICS matrices.
mitreattack-python, attackcti, stix2 librariesThe ATT&CK Enterprise matrix organizes adversary behavior into 14 Tactics (the "why") containing Techniques (the "how") and Sub-techniques (specific implementations). Each technique has associated data sources, detections, mitigations, and real-world procedure examples from observed threat groups.
ATT&CK catalogs over 140 threat groups (e.g., APT28, APT29, Lazarus Group, FIN7) with documented technique usage. Each group profile includes aliases, targeted sectors, associated campaigns, software used, and technique mappings with procedure-level detail.
The ATT&CK Navigator is a web-based tool for creating custom ATT&CK matrix visualizations. Analysts create layers (JSON files) that annotate techniques with scores, colors, comments, and metadata to visualize threat actor coverage, detection capabilities, or risk assessments.

Going by SKILL.md and its folder, ATT&CK Threat Actor Mapping needs Python for the scripts in its folder. Our summary lists: Python 3.9 or newer with mitreattack-python, attackcti and stix2; ATT&CK Navigator, web-based or local.
SKILL.md names 3 domains. As links in the text: attack.mitre.org, github.com and mitre-attack.github.io. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
ATT&CK Threat Actor Mapping is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.5k tokens (SKILL.md is roughly 10k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.6k tokens, read only when the agent opens those files.
