Change of default anti malware policy

We're an MSP and Redscan SOC notified us of an update to the default anti malware policy on our tenant and those of each of our other customers under their service:

Date / Time: 2023-05-16T07:56:09.163+00:00
Origin User: system
Command: set-malwarefilterpolicy

{"name":"domaincontroller","value":""},
{"name":"ispolicyoverrideapplied","value":"true"},
{"name":"filetypeaction","value":"reject"}

Other than tenant details, the alerts are identical.

This appears to be a product update, but we'd like to confirm if possible before closing out the alerts.
