RPCMon - RPC Monitor Tool Based On Event Tracing For Windows

A GUI tool for scanning RPC communication through Event Tracing for Windows (ETW). The tool was published as part of a research on RPC communication between the host and a Windows container.

Overview

RPCMon can help researchers to get a high level view over an RPC communication between processes. It was built like Procmon for easy usage, and uses James Forshaw .NET library for RPC. RPCMon can show you the RPC functions being called, the process who called them, and other relevant information.
RPCMon uses a hardcoded RPC dictionary for fast RPC information processing which contains information about RPC modules. It also has an option to build an RPC database so it will be updated from your computer in case some details are missing in the hardcoded RPC dictionary.

Usage

Double click the EXE binary and you will get the GUI Windows.
RPCMon needs a DB to be able to get the details on the RPC functions, without a DB you will have missing information.
To load the DB, press on DB -> Load DB... and choose your DB. You can a DB we added to this project: /DB/RPC_UUID_Map_Windows10_1909_18363.1977.rpcdb.json.

Features

  • A detailed overview of RPC functions activity.
  • Build an RPC database to parse RPC modules or use hardcoded database.
  • Filter\highlight rows based on cells.
  • Bold specific rows.

Credit

We want to thank James Forshaw (@tyranid) for creating the open source NtApiDotNet which allowed us to get the RPC functions.
