<p>Detects anomalous Kerberos activity such as forged or stolen tickets by correlating malformed fields in logon events, RC4-encrypted TGTs, or TGS requests without corresponding TGT requests. Also detects suspicious processes accessing LSASS memory for ticket extraction.</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: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 |
|---|---|
TicketLifetimeThreshold | Threshold for Kerberos TGT lifetimes deviating from domain defaults. |
EncryptionTypes | Monitor for downgraded encryption types (e.g., RC4) in Kerberos tickets. |
ProcessAllowlist | List of expected processes accessing LSASS; deviations may be suspicious. |
