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:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
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 |
|---|---|
InstallerParent | Could be msiexec.exe or third-party wrapper like setup.exe. |
ChildImagePath | Payload paths vary based on where installer extracts to (e.g., %TEMP%, C:\Users\Public). |
ExecutionTimeWindow | Threshold for how soon a payload must run after msiexec to be considered related. |
