Blocking entirely a file type like .js .vbs .hta .ps1 etc is what I call hardening a system and a smart approach: if a script is known to be commonly abused to deliver malware and it is not widely used or not strictly needed, then block it and problem solved. No need to check if the script is malicious or not, the user can write exclusion rules if needed.
Same approach goes for commonly abused system processes like powershell.exe, certutil.exe, mshta.exe, bash.exe, etc.
Do you think so? Instead I think it is very good for hardening a system by blocking/disabling what is not needed, thus reducing the attack surface and the malware delivery methods.
If you need to execute a script that is blocked you can write exclusion rules, that's all.
I joined the conversation not to discuss about the topic but about this:
I personally believe there are probably better ways and words to express your opinion.
Because to me it sounds as you said "OS Armor blocks by file type" -> "blocking something by file type is really, really, really stupid."

Globally blocking anything by file type without context is very stupid.

VS blocks by context and OS Armor blocks by file type. There is a HUGE difference between the two.
I have said this a million times... please understand that blocking something by file type is really, really, really stupid.
