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 | DYLD event subsystem | DC0016 Module Load |
| fs:fsusage | File Access Monitor | DC0055 File Access |
| macos:osquery | Memory Mappings | DC0020 Process Modification |
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 |
|---|---|
DYLDInjectedPath | Tunable based on naming patterns or location of malicious dylibs |
ParentProcessName | Hooking attempts may stem from terminal.app, bash, or AppleScript-based launchers |
