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 | execution of curl, osascript, or unexpected Office processes | DC0032 Process Creation |
| macos:unifiedlog | file read of sensitive directories | DC0055 File Access |
| macos:unifiedlog | HTTPS POST requests to pastebin.com or similar | DC0078 Network Traffic Flow |
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 |
|---|---|
WatchedApps | Processes not normally associated with data uploads (e.g., Preview, Calculator). |
EntropyThreshold | High entropy detection to flag encoded or encrypted data exfiltration. |
