Defender: Exploit of HAFNIUM on newest MS Exchange Version?

Hi all,

I'm running an exchange on Windows Server 2022, on Exchange Build 15.2.1544.14 (Nov 2024 CU) I've just received an MS Defender EDR High Incident of possible infection of the exchange server.

I've checked the Version and Patchmanagement, everything looks fine, even Defender says in the device page "missing kbs" that there is nothing to update.

Can I ignore that? I'd say yes, but why would defender create a high incident for that?

    There are several useful scripts here:
    Microsoft - CSS-Exchange
    Run the health checker first, it should provide more information on areas within Exchange that need adjusting.
