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 | Received messages containing embedded links or attachments from non-enterprise services | DC0038 Application Log Content |
| macos:unifiedlog | Execution of osascript, bash, or Terminal initiated from Mail.app or Safari | DC0032 Process Creation |
| macos:unifiedlog | Suspicious outbound HTTPS requests to domains flagged as newly registered or untrusted after spearphishing message interaction | 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 |
|---|---|
CertificateChecks | Flagging mismatched or self-signed certificates during outbound connections initiated after spearphishing messages. |
ExecutionDelay | Window of time between attachment download and subsequent suspicious execution. |
