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:unified | MailSend: Outlook messages with suspicious subject/body terms (e.g., urgent payment, wire transfer) targeting finance teams | DC0038 Application Log Content |
| m365:office | Anomalous editing of invoice or payment document templates | DC0061 File 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 |
