The domain mail.user-coinbase.support was identified as a brand‑impersonation infrastructure targeting Coinbase users. Analysis shows the site resolved to IP 188.114.97.3, which is hosted within the US under ASN 13335 belonging to Cloudflare, Inc. The server presented a Google Trust Services / WE1 SSL certificate and responded with HTTP 403, while Cloudflare and HTTP/3 were detected in the transport stack. A passive scan on VirusTotal recorded three positive detections out of ninety‑five AV engines, and the domain appears on a single security blocklist.
PhishDestroy has confirmed the site is taken offline, and current DNS queries return no nameserver data (NS_NOT_FOUND). The only visible artifact is the page title "Roundcube Webmail :: Bem‑vindo ao Roundcube Webmail," suggesting a generic mail interface rather than a Coinbase‑specific login page. Registration information lists Cloudflare, Inc. as the registrar, with no additional registrant details disclosed.
Because the service is no longer reachable, direct content analysis is limited, leaving uncertainty around the exact phishing page layout and any credential‑harvesting mechanisms that may have been employed. Defenders should continue to block the IP address and the domain at perimeter controls, monitor for re‑registration or similar sub‑domains, and incorporate the observed SSL fingerprint and HTTP status into detection rules. Users should be warned that any unsolicited communications referencing Coinbase that direct to this domain are malicious, and credential reuse across services must be avoided.

For the registrable domain user-coinbase.support behind this subdomain, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.
Accreditation is a contract, not a safety certification.
RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.

Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.
