kavanoz - Statically unpacking common android banker malware

项目说明

🫙 kavanoz 🫙

Kavanoz (jar in turkish) is a tool to statically unpack common android banker malware.
Do you e to get payload from packed malware without running android emulator ? Me neither :) But here is a tool anyway.


:eyes: Installation

To install from source, clone the repository and do an editable install with -e. Which means if you edit or add new plugins to the project it will be used without reinstalling.

:zap: Usage

from cmdline

You can use -vvv parameter to print logs. (useful for debugging plugins)

as python library

:snake: Scripts:

:gear: De

Make sure to install kavanoz as editable (with -e). To add new plugins just create new file in loader folder. Extend Unpacker class from unpack_plugin.py file. Define start_decrypt function with your implementation.

Add following function to make early exit from plugin.

If extraction is successful assign self.decrypted_payload_path with extracted file path.
You can use helper functions from unpacker class:

Make sure to run python -m unittest before opening a PR. In order to get test apk files, use git lfs pull command.
