What it does
Once installed, the agent can take a threat actor's known behaviours or observed indicators and map them to techniques in the MITRE ATT&CK knowledge base, a public catalogue of how real attackers operate. It can generate ATT&CK Navigator layer files (colour-coded heatmaps of techniques), compare several threat groups, and point out where a defender's detections may not cover the observed behaviour. The skill also includes a Python script that fetches ATT&CK data from MITRE's servers and produces these outputs.
Great for
- Security analysts writing threat intelligence reports on a specific adversary group
- Detection engineers checking which observed techniques lack monitoring coverage
- Students learning how ATT&CK, STIX data and Navigator fit together
Skip it if
- Live incident response where speed matters more than mapping rigour, since the workflow is report-oriented and needs analyst review
- Organisations that cannot send queries to MITRE's servers or GitHub, because the default script downloads data from the internet
- Readers expecting authoritative attribution: the skill maps described behaviour to techniques but does not establish who is responsible for an attack
Try asking
- “Map the techniques used by APT29 and generate a Navigator layer I can open in the ATT&CK Navigator”
- “Compare the TTPs of APT28, APT29 and Lazarus Group and summarise the overlaps”
- “Given these IOCs and log observations, which ATT&CK techniques do they correspond to and what detection gaps remain?”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Review generated Navigator layers and mapped techniques before sharing; automated mapping from descriptions can be imprecise.
- Supply a local copy of the ATT&CK STIX bundle to avoid repeated network downloads and to pin a specific ATT&CK version.
- Provide your own detections file when asking for gap analysis so the output reflects your actual coverage.
