Structured Threat Information Expression (STIX) is a language and serialization format used to exchange cyber threat intelligence (CTI). STIX enables organizations to share CTI with one another, including malware analysis information, in a consistent and machine-readable manner.
Details on how MBC data maps to STIX 2.1, as well as information on how to query and manipulate MBC data and how to use the MBC Content in the ATT&CK® Navigator, is given in USAGE.md.
