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 | Repeated process crashes logged by CrashReporter or system instability logs in com.apple.console | DC0038 Application Log Content |
| macos:unifiedlog | Spike in CPU or memory use from non-user-initiated processes | DC0018 Host Status |
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 |
|---|---|
CrashCountThreshold | Number of app crashes within monitoring window |
PayloadEntropyThreshold | Used for high-entropy binaries often observed in DoS malware samples |
