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=3033 | DC0016 Module Load |
| WinEventLog:Sysmon | EventCode=6 | DC0079 Driver Load |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=2 | DC0061 File Modification |
| WinEventLog:Sysmon | EventCode=12 | DC0056 Windows Registry Key Creation |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
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 |
|---|---|
TimeWindow | Correlate DLL file creation/modification with LSASS execution within a configurable timeframe (e.g., 5 min) |
ImagePathPattern | Tune based on known legitimate LSASS plugin DLL paths |
SignatureValidation | Flag unsigned DLLs loaded into lsass.exe or those signed by unexpected publishers |
RegistryKeyScope | Scope to specific registry keys: HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Authentication Packages |
FileHashAllowList | Exclude known-good LSASS plugin DLLs based on cryptographic hash |
