<p>Detects forged Kerberos Silver Tickets by identifying anomalous Kerberos service ticket activity such as malformed fields in logon events, TGS requests without interaction with the KDC, and access attempts using service accounts outside expected hosts/resources. Also monitors suspicious processes accessing LSASS memory for credential dumping.</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| WinEventLog:Security | EventCode=4672, 4634 | DC0088 Logon Session Metadata |
| WinEventLog:Kerberos | Kerberos TGS-REQ anomalies without KDC validation (Silver Ticket behavior) | DC0084 Active Directory Credential Request |
| WinEventLog:Sysmon | EventCode=10 | DC0035 Process Access |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
ServiceAccountScope | Expected mapping of service accounts to specific resources; deviations may indicate Silver Ticket use. |
TicketValidationBaseline | Expected TGS issuance patterns including KDC validation; anomalies may signal forged tickets. |
ProcessAllowlist | Known processes that legitimately interact with LSASS; others may indicate dumping attempts. |
TimeWindow | Correlate Kerberos requests within a tunable timeframe to reduce false positives. |
