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 | Outgoing or incoming calls with non-standard caller IDs or unusual metadata | DC0038 Application Log 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 |
|---|---|
CallerIDPatterns | Patterns of spoofed caller IDs that must be tuned based on region and telecom provider |
PayloadCorrelation | Define what follow-on events (browser downloads, execution) to correlate with call logs |
