Evasion Technique - 3348100960

“Behavior of hiding RWX code by modifying it to RX”

I've been seeing this alert that is considered high criticality and is blocking Windows updates.

 

Everything I can see says that this is benign.

XDR is saying that the Windows process is a non-whitelist CGO. I've verified that this is the legitimate Microsoft WerFault.exe

There is no description of what is triggering this alert, there is no description of this evasion technique, and the causality chain is very little help.

I've also verified that the behavior is caused when a user tries to update, or an automatic update starts.

Is anyone having a similar issue where XDR is blocking Windows updates?
