Suspected suspicious Kerberos ticket request on one endpoint

Hi

The documentation for the alert “Suspected suspicious Kerberos ticket request on one endpoint”  with 

UniqueExternalId  2418 seems to be missing.

The alert references https://aka.ms/suspiciouskerberosticketrequest, which  leads to the Bing search engine page.

Nothing here either:
https://docs.microsoft.com/en-us/defender-for-identity/suspicious-activity-guide

Is there any further documentation available or planned?

Thanks
