Has anyone seen this behavior with Sysmon: getting non-English characters in the ParentUser, and ParentCommandLine fields? Sometimes it looks like another language character set, other times it is WingDings or some other non-sensical characters. This screenshot is from our enterprise Splunk (~30,000 endpoints) and is a screenshot of 2 devices over a 60 minute sampling window. The one theme I see when digging into the Splunk record for each of these events is that the ServicePrincipleName begins with "TERMSRV/" and then the rest of the SPN follows. Only happens with Event code = 1.
