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 | logd:file write | DC0039 File Creation |
| macos:endpointsecurity | ES_EVENT_TYPE_NOTIFY_EXEC | DC0032 Process Creation |
| macos:osquery | mach_o_info, file_metadata | 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 |
|---|---|
ScriptFormatType | Run-only AppleScripts or signed scripting payloads may require scoped detection |
DroppedBinaryCount | Threshold on number of binaries created by the parent payload |
ParentProcessName | Allows focusing on suspicious interpreter or staging tools |
