Type Name Severity Module Data source / event ATT&CK
Analytics A new machine attempted Kerberos delegation A newly created machine attempted to perform a Kerberos delegation. This suspicious activity might indicate a Kerberos relay attack. Medium Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Privilege Escalation
Analytics A user printed an unusual number of files A user printed an unusual number of files. This may be indicative of malicious activity and an attempt to exfiltrate data. Informational Identity Threat Detection (ITDR) Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Exfiltration
Analytics A user received multiple weakly encrypted service tickets A user received multiple weakly encrypted service tickets. This is typically a sign of a Kerberoasting attack. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics A user requested multiple service tickets A user requested multiple service tickets. This is typically a sign of a Kerberoasting attack. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics A user sent multiple TGT requests to irregular service A user sent multiple TGT requests to services other than KRBTGT and KADMIN. This is typically a sign of a Kerberoasting attack. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics Excessive user account lockouts A high amount of user accounts were locked out from a single source host in a short time period. This may be the result of a brute-force or password spray attack. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics Local group enumeration A user performed an enumeration on local groups to retrieve their details. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics Multiple suspicious user accounts were created A user was observed creating multiple rare user accounts. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Persistence
Analytics Multiple TGT requests for users without Kerberos pre-authentication Multiple TGT requests for users that do not require Kerberos pre-authentication were observed. This is typically a sign of an AS-REP attack. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics Multiple user accounts were deleted A user deleted multiple user accounts. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Persistence, Impact
Analytics Possible Privilege Escalation using Delegated MSA account An attacker might abuse dMSA account to escalate its privileges. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Privilege Escalation
Analytics Short-lived user account A user was created and deleted within a short period of time. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Defense Evasion
Analytics Single account excessively locked out A user has been locked out an unusually high number of times within a short timeframe. This could indicate an attempt to gain unauthorized access to the user's account. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics User added to a group and removed A user was added to an Active Directory group and removed within a short period of time, which may be a sign of compromise. Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Persistence, Privilege Escalation
Analytics User added to the SMS Admins local group A user was added to the SMS Admins local group. This may indicate a potential attack targeting the Microsoft Configuration Manager infrastructure. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Persistence, Privilege Escalation
