<p>Identifies archive utilities (e.g., ditto, unzip, xar, pkgutil) used to extract payloads to non-standard paths, then correlates with execution or file permission changes (e.g.,
chmod +x) and process spawns from decompressed location.</p>- Detects

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 | Process launch | DC0032 Process Creation |
| macos:unifiedlog | filesystem events | DC0059 File Metadata |
| fs:fsusage | file open/write | 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 |
|---|---|
DecompressionPathMatch | Target unusual extraction paths (~/Library/, /tmp/, /private/tmp/) |
ToolBinaryNames | List of decompression utilities used in the environment |
FollowOnExecutionDelta | Time between decompression and first binary execution |
