AN1037 Analytic 1037
macOS · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Detects tampered Mac hardware/firmware by analyzing unified logs, EndpointSecurity events, and Apple Mobile File Integrity (AMFI) checks. Behavioral chain: (1) Boot process reports firmware signature mismatch; (2) Secure Boot policy altered; (3) new EFI drivers or hardware devices appear in inventory; (4) system extension loads from unapproved developer IDs post-boot.</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 | EFI firmware integrity check failed | DC0018 Host Status |
| macos:endpointsecurity | es_event_authentication | DC0059 File Metadata |
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 |
|---|---|
AllowedTeamIDs | Developer Team IDs approved for kext/system extension loads. |
FirmwareVersionBaseline | Expected EFI/firmware version for Mac model. |
