BinjaDock allows you to create dockable widgets in Binja and exposes a main dockwidget with tabs for plugins to embed to.
Yarascan is an example plugin demonstrating how to use BinjaDock.
Put it in the plugins folder...
To use the included yara example plugin you will need to supply your own yara signatures and define them in SIG_FILE in yarascan.py. You may find the crypto signatures and many more (AntiVM, malware, packers, exploit kits) here.
BinjaDock has only been tested on Ubuntu 16.04 using Qt and PyQt5 packages from the official ubuntu repositories.
