FileSystem Minifilter Windows - Strategy to store data before services are running

dlionisdlionis Member Posts: 1

I am creating a FS minifilter driver that aims to list DLL files loaded by all services. So far it works: in the INF file, I set the startup type of the filter to

0x00000001 SERVICE_SYSTEM_START

, meaning that the filter is run before all services are.

As I need to retrieve all loaded DLLs by all services from the first time they are run, I had to make this driver loaded at SYSTEM_START. I would then create a port with my minifilter to communicate and send data to my software (a service).

This is the issue: how can I send data from a minifilter that starts before services are running (my service won't be running yet when my minifilter will be)?

Thank you.
