Last year i wrote a blogpost about how to get all the powershell scripts used as detection methods and since then i have refined that script a bit and also added logic for it to now output any detection method using scripts regardless if its Powershell, VBScript or Javascript.
I hope this can be useful to someone out there in cyberspace.

Example
You need to run script locally from your siteserver.
get-DetectionMethodScripts.ps1 -DestinationPath "C:\temp\scripts\"
and it will output all the detection methods that uses scripts to that folder. One for each application and names the file after the application.
Until next time, cheers !
