MAEC 3.0 is now available!

Kirillov, Ivan A.

All,

 

I’m pleased to announce that version 3.0 of the MAEC language is now available:

 

http://maec.mitre.org/language/version3.0/

 

MAEC v3.0 represents a major version of the MAEC language, and consists of three XML schemas:

  • Version 3.0 of the MAEC Bundle schema, a revised version of the v2.1 MAEC core schema, which also defined the Bundle. A MAEC Bundle is intended to capture all of the analysis derived characteristics for a single malware instance, including any observed MAEC Behaviors or Actions, and any related MAEC Objects.
  • Version 1.0 of the new MAEC Package schema. A MAEC Package is intended to characterize all known data for one or more malware instances, including their analysis derived characteristics (via MAEC Bundles) and any associated analysis or other metadata.
  • Version 1.0 of the new MAEC Container schema. A MAEC Container is intended to serve as a transport mechanism for one or more MAEC Packages.

Some of the new features in MAEC 3.0 include:

  • A significant structural re-organization of functionality and scope through the multiple MAEC schemas, thus permitting the use of only the particular schema(s) that are relevant to the individual end-user.
  • The ability to capture equivalences between identical Actions and Objects, for use as a single units as well as analytical observations, through the new MAEC Package.
  • The ability to explicitly capture the process tree for an executed malware instance, through the revised MAEC Bundle.
  • Many revisions to existing types, for the purpose of streamlining and clarifying their intent and use.
  • The import and usage of the Cyber Observables Expression (CybOX) v1.0 final.

For more information please see the detailed release notes or schema annotations linked to on the release page; also included are many more examples that are intended to highlight the new structures and features in MAEC v3.0. We welcome your comments, feedback, and questions.
