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 | com.apple.mail.* exec.* | DC0032 Process Creation |
| macos:unifiedlog | curl|osascript.*open location | DC0085 Network Traffic Content |
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 |
|---|---|
ExecutionChainDepth | Number of child processes stemming from Mail.app |
MailScriptFlag | Toggle on scripting detection within mail context |
