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 | quarantine or AV-related subsystem | DC0038 Application Log Content |
| macos:osquery | file_events | DC0059 File Metadata |
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 |
|---|---|
BinaryChangeThreshold | File hash delta or binary string diff score to tolerate renamed/mutated variants. |
UserContext | User or group expected to use dev tools; reduce false positives from legitimate repacking. |
