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 | log stream --predicate 'processImagePath contains "zip" OR "base64"' | DC0064 Command Execution |
| macos:osquery | file_events | 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 |
|---|---|
FilenameExtensionList | Tunable to identify uncommon or encrypted file formats (e.g., .enc, .b64, .xz) |
UserContext | Tune to prioritize unexpected file access by service accounts |
