I Introduction

Since Alex Ionescu and Gabrielle Viala Blackhat2018 talk on Windows Notification Facility (https://www.youtube.com/watch?v=MybmgE95weo) there has been several posts on this topic.
Modexp wrote a nice proof of concept of executing remote code via WNF callback in explorer.exe (https://modexp.wordpress.com/2019/06/15/4083/).

In this paper, I am taking this WNF code injection POC and generalize it so that is works with any process.
