This repository provides MITRE ATT&CK and CAPEC datasets formatted in STIX 2.0 standard for cybersecurity threat intelligence sharing and analysis. The repository contains structured threat intelligence data that represents adversary tactics, techniques, and procedures (TTPs) from the MITRE ATT&CK framework, as well as Common Attack Pattern Enumeration and Classification (CAPEC) data. The datasets are expressed using the Structured Threat Information Expression (STIX) 2.0 format, which enables standardized sharing and consumption of cyber threat intelligence across different security tools and platforms. Users can work with this content using the python-stix2 library for programmatic access and manipulation of the threat intelligence data. The repository serves as a foundational resource for security professionals who need standardized threat intelligence data for threat hunting, detection rule development, risk assessment, and security analytics applications. Both ATT&CK and CAPEC datasets are maintained and updated with new releases to ensure current threat landscape coverage.
