The Microsoft Defender Security Center Threat & Vulnerability Management security recommendations refer to "Block persistence through WMI event subscription" as an action to be taken to reduce the attack surface.
Creating an Attack Surface Reduction profile via the Microsoft Endpoint Manager admin center does not show "Block persistence through WMI event subscription" as a configuration option.
The only WMI related option is "Block process creations originating from PSExec and WMI commands"?

Same here....
And here
Dear @SteffanH ,
the option "block persistence through wmi event subscription" is not available (or not available yet) in Intune. I created a PR to fix this in the article.
You can enable this rule using PowerShell or GPO.
Thank you
@MaratMussabekov , where can I find documentation how to enable this via PowerShell?
Hello @SteffanH ,
please see this article.
Thank you
Not sure why this was assigned to me? It's not an area I know anything about and isn't my article.
@jaimeo Apologies for the mistake from my end. The issue should in fact be closed as it has been answered by Marat. Thank you.
You can simply use a custom Configuration Profile in Intune with the CSP GUID for the ASR rule.
OMA-URI: ./Vendor/MSFT/Policy/Config/Defender/AttackSurfaceReductionRules
Data type: String
Value: {e6db77e5-3df2-4cf1-b95a-636979351e5b}=1
This shouldn't be closed.
The policy is still not available via Endpoint Manager.
And I personally don't want to write up an entire ASR Rule into a String to use for a Policy CSP.
When will this ARS rule be possible to set via Endpoint Manager?
When will this ARS rule be possible to set via Endpoint Manager?
