We have posted content for doing Notepad++ IoC checks. A fixlet and analysis. They are available here: content/solutions/notepad_plus_plus at master · bigfix/content · GitHub
This also does a basic check for Notepad++ installs in the analysis.
This is not based upon this script: GitHub - nHunter0/Notepad-vulnerability-checker
and is instead something developed internally by one of our team members.
