DLL hijacking discovery using Procmon and writable search paths

April 4, 2026r/AskNetsec

In r/AskNetsec, defenders explain that Procmon Name Not Found is only a starting signal for DLL hijacking, and the real test is whether the loader search order includes user-writable paths and unsigned DLL loads.

but how do you actually find vulnerable apps? like do i just run procmon and look for “name not found”? feels too simple.
Basically. That and DLLs loaded from unsafe locations, ie locations that you have write access to.
Procmon Name Not Found is the start, not the finish. I look for missing loads plus writable search paths, weird CWD behavior, manifests, and SafeDllSearchMode.

What you are really hunting is the intersection of 3 things: missing DLL lookups, actual Windows loader search order for that process, and whether any searched path is user writable.
