The STIX 2.0 JSON content found here is the unabridged conversion of the MITRE ATT&CK catalog in its entirety. All of the converted STIX Objects can be found individually in all the subdirectories enumerated here (i.e. organized by STIX object type) or compiled in a single json file (mitre-attack.json).

ATT&CK -> STIX 2.0 Mapping (High-Level)

ATT&CK Technique -> STIX Attack-Pattern
ATT&CK Tactic -> STIX Attack-Pattern.Kill-Chain-Phase, STIX Tool.Kill-Chain-Phase, STIX Malware.Kill-Chain-Phase
ATT&CK Group -> STIX Intrusion-Set
ATT&CK Software -> STIX Malware (OR) STIX Tool
ATT&CK Mitigation -> STIX Course-of-Action

ATT&CK -> STIX 2.0 Mapping (Detailed)

Bold signifies data pulled from ATT&CK model objects

(Custom) signifies STIX object properties that are not apart of the standard STIX 2.0 data model but were added for further fidelity in the mapping from ATT&CK.

Intrusion-Set.external_references = References from ATT&CK

ATT&CK Software -> STIX Malware (OR) STIX Tool

Malware.type = "malware"

ATT&CK Mitigation -> STIX Course-of-Action

Course-of-Action.type = "course-of-action"
Course-of-Action.id = "course-of-action-uuid"
Course-of-Action.created = [date created]
Course-of-Action.modified = [date modified]

All translated ATT&CK - STIX objects are tagged with an external reference linking to the corresponding ATT&CK object (Tactic, Technique, Software, Group) and webpage that it stems from. For example:

This STIX Tool object has an external reference linking to S0006, the ATT&CK object it was translated from. The other external reference is the citation from the Software page.

Life Cycle

As the MITRE ATT&CK catalog - to include Tactics, Techniques, Groups, Software, and Mitigations - is further developed and expanded, so to will this repository of translated STIX content. Any modification to the ATT&CK catalog triggers an immediate process to assess and update the existing STIX content found here.

Explicit concern is paid to the maintenance of the STIX Object versions. All converted ATT&CK content follows the STIX versioning policy (read the docs: https://oasis-open.github.io/cti-documentation/).
