@nprofile1q... @nprofile1q... Indicators of compromise of users would look like post exploit behavior of an RCE vuln in the auto updater process... I haven't looked at details, but if you have process logging (4688s), if you find processes started by the notepad++ process, that is your haystack (not all updates would have been targeted, let's say...) to find the needles, you'll need to go hunting for the malicious update returned by hostile auto updater service.
