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 | launchctl load/unload or plist file modification | DC0064 Command Execution |
| fs:fsusage | file write to launchd plist paths | DC0061 File 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 |
|---|---|
PlistPathList | Watched directories for LaunchDaemons and LaunchAgents |
PlistKeyMonitor | Monitored keys such as `RunAtLoad`, `KeepAlive`, or `ProgramArguments` |
UnsignedBinaryAlert | Flag execution of unsigned or non-Apple-signed binaries within plist |
