capa v1.6.0


Recommended Posts

v1.6.0 (2021-03-09)

This release adds the capa explorer rule generator plugin for IDA Pro, vivisect support for Python 3 and 12 new rules. We appreciate everyone who opened issues, provided feedback, and contributed code and rules. Thank you also to the vivisect development team (@rakuy0, @atlas0fd00m) for the Python 3 support (vivisect==1.0.0) and the fixes for Python 2 (vivisect==0.2.1).

Rule Generator IDA Plugin

The capa explorer IDA plugin now helps you quickly build new capa rules using features extracted directly from your IDA database. Without leaving the plugin interface you can use the features extracted by capa explorer to develop and test new rules and save your work directly to your capa rules directory. To get started select the new Rule Generator tab, navigate to a function in the IDA Disassembly view, and click Analyze. For more information check out the capa explorer readme.


Upcoming changes

This is the last capa release that supports Python 2. The next release will be v2.0 and will have breaking changes, including the removal of Python 2 support.

If you have workflows that rely on the Python 2 version and need future maintenance, please reach out. We may be able to supply limited backports of key fixes and features.
