Summary of the Pull Request
According to Microsoft, threat actors used a .url internet shortcut that points to a JavaScript file in the Startup folder. As a result, I added the .url extension. While reviewing the rule, I also realized we could include more suspicious extensions, so I added them as well.
Changelog
update: Suspicious Startup Folder Persistence: add more suspicious extensions
