v1.5.0 (2021-02-05)
This release brings support for running capa under Python 3 via SMDA, more thorough CI testing and linting, better extraction of strings and byte features, and 50 (!) new rules. We appreciate everyone who opened issues, provided feedback, and contributed code and rules. A special shout out to the following new project contributors:
@dzbeck also added Malware Behavior Catalog (MBC) and ATT&CK mappings for many rules.
Download a standalone binary below and checkout the readme here on GitHub. Report issues on our issue tracker and contribute new rules at capa-rules.
