The document summarizes the Cyber Analytics Repository (CAR), an openly available repository of ATT&CK-driven analytics maintained by MITRE. CAR contains analytics for detecting adversary tactics and techniques, mappings of analytics to sensors, and an exploration tool. Recent work has focused on increasing quality and usability by adding new analytics, converting analytics to a machine-readable format, and supporting multiple implementations. Future goals include expanding coverage of ATT&CK techniques, updating the data model and sensor coverage, and improving the analytic exploration tool. The document encourages contributions of new analytics to CAR.
