Protobuf Finder

IDA plugin for reconstructing original .proto files from binary.

Installation

1. Install Google protobuf python library - $ pip install protobuf
2. Copy protobuf.py into IDA plugins folder - ~/.idapro/plugins/

Usage

After loading the binary that contains Protocol Buffer specifications use Search > Protobuf Finder. This will spawn a custom view for each .proto file that was used to build the binary.

Special Thanks
