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 |
|---|---|---|
| macos:unifiedlog | Repetitive inbound email delivery activity logged within a short time window | DC0038 Application Log Content |
| fs:fsusage | create: Attachment file creation in ~/Library/Mail directories | 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 |

FileCountThreshold | Threshold for repetitive attachment files created within a defined interval. |
