<p>Detects DHCP spoofing by monitoring unified logs for unexpected DHCP ACK/OFFER parameters and correlating with packet captures for multiple DHCP servers. Behavioral emphasis is on inconsistent DNS and gateway assignments that redirect traffic.</p>

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 | new DHCP configuration with anomalous DNS or router values | DC0038 Application Log Content |
| NSM:Flow | Multiple DHCP OFFER responses for a single DISCOVER | 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 |
|---|---|
BaselineDNS | Expected DNS server list; deviations may indicate spoofing. |
AlertSensitivity | Threshold for number of anomalous DHCP responses before alerting. |
