<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.

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.

FieldDescription
ServiceAccountScopeExpected mapping of service accounts to specific resources; deviations may indicate Silver Ticket use.
TicketValidationBaselineExpected TGS issuance patterns including KDC validation; anomalies may signal forged tickets.
ProcessAllowlistKnown processes that legitimately interact with LSASS; others may indicate dumping attempts.
TimeWindowCorrelate Kerberos requests within a tunable timeframe to reduce false positives.
