{"success":true,"data":{"id":"brand-dkim-none","label":"Brand Domain, DKIM Absent","description":"Email claims to be from a known brand domain (PayPal, Google, Microsoft, Amazon, etc.) but carries dkim=none — no DKIM signature at all. Every major brand has published DKIM records since 2015+; a brand domain that cannot produce a DKIM signature was not sent through the brand's own infrastructure. This is a strong spoofing indicator distinct from dkim=fail: the attacker did not even attempt to forge a signature.","tier":"danger","category":"header","isThin":false}}
