David Cowen Sunday Funday Challenge - Docker Containers on WSL Artifacts - Part 2

by ogmini

Getting some work done on this challenge; but I am not very confident that I’ll find much before the deadline. As a quick note for anyone else trying to run Docker or really anything that results in nested virtualization. You need to set ExposeVirtualizationExtensions to true for Hyper-V https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/nested-virtualization.

As always, I’m using Process Monitor, Process Explorer, and TCPView to keep an eye on activity while performing testing. Some locations of interest that have already surfaced:

Folder Location Comments
%localappdata%\Docker\log Contains logs
%localappdata%\Docker\wsl Contains vhdx files related wot WSL and Containers
%userprofile%\.docker\contexts\meta  

The com.docker.backend.exe.log file is of great interest as we can see all the events going on with containers and so forth. For example the line:

[2025-04-10T20:27:47.539553700Z][com.docker.backend.exe.ports] exposer.Add(de1d1ec90a81dff7dc48705fbf17c81ec6c4717da6df1056f65360e8049aacd9, /great_matsumoto, [])

Shows us the running of a container which got the name of great_matsumoto.

Matsumoto Frog

That’s as far as I got—there’s still more to look into, but it’s a start.
