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 |
|---|---|---|
| m365:office | VBA auto_open, auto_close, or document_open events | DC0029 Script Execution |
| m365:office | External HTTP/DNS connection from Office binary shortly after macro trigger | DC0085 Network Traffic Content |
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 |
|---|---|
MacroFunctionNames | Names of event-bound functions like Auto_Open that initiate execution |
TimeDeltaMacroToC2 | Time threshold to correlate macro execution with outbound connections |
