is there a way to create an alert to detect the movement of files that have a mismatched file extension?

i know Netskope will do its inspect of the file but i would like an alert on this as an indicator of risky behavior.

What is your concern here - unacceptable/shady behavior or data/malware risk ?
Sounds like the former.. but thought I'd ask - The one way I'm thinking is using NAA to regex the object name (to extract the extension from the object name) and compare against the file type that we detect - but that's manual..

You can also try to create a realtime policy for certain categories or applications, and apply file type constraints for upload and download activities to identify risky file type uploads and downloads.
