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 |
|---|---|---|
| Application:Mail | Inbound emails containing hyperlinks from suspicious sources | DC0038 Application Log Content |
| auditd:SYSCALL | execve: Execution of scripts or binaries spawned from browser processes | DC0032 Process Creation |
| NSM:Flow | Outbound requests to domains not previously resolved or associated with phishing campaigns | 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 |
|---|---|
MonitoredBrowsers | List of browser processes to monitor (e.g., firefox, chrome, chromium). |
PhishingIndicators | Custom regex patterns for detecting obfuscated or IDN homograph URLs. |
