Not Petya Ransomware

I would love to know this as well.

So yes..

Assuming the UTM 9.4.x Email protection detects those signatures.

I didn't see anything about the emails being blocked yet, just that any Sophos Endpoint can prevent infection if properly configured.

A temporary solution to prevent NotPetya encryptions for Systems Administrators is to create then push a Read-Only file called perfc to C:\Windows using a GPO. After creating the GPO run a gpupdate /force on your Domain Controller.
