Analysis of the domain webmail.warranty-coinbase.com shows a newly registered infrastructure used to impersonate the Coinbase brand in a crypto‑related scam. The domain was created on 2025‑10‑18 and is hosted behind Cloudflare, as indicated by the presence of Cloudflare Browser Insights, the Cloudflare service itself, and HTTP/3 support. DNS resolution points to IP address 104.21.66.182, which belongs to AS13335 Cloudflare, Inc. and is located in the United States. The authoritative name servers are kevin.ns.cloudflare.com and maria.ns.cloudflare.com, confirming the use of Cloudflare’s DNS services. The site presented a Roundcube Webmail login page, as reflected in the page title "Roundcube Webmail :: Welcome to Roundcube Webmail," but the HTTP response returned a 403 status code, suggesting that the front‑end is presently inaccessible or deliberately blocked.
Security‑vendor intelligence flags the domain as malicious: eleven out of ninety‑five VirusTotal scanners flagged it, and it appears on one external blocklist. The PhishDestroy blocklist has already taken the domain offline, and the current status is reported as offline. The SSL certificate is issued by Google Trust Services under the WE1 profile, indicating a valid TLS handshake but providing no assurance of legitimacy. Registration was performed through Dynadot LLC, a registrar commonly used for both legitimate and abusive registrations.
Defenders should treat this domain as a confirmed crypto‑scam indicator. Immediate actions include adding the domain and its resolving IP address (104.21.66.182) to web‑filter blocklists, updating intrusion‑prevention signatures, and monitoring for any new subdomains that share the same registrar or Cloudflare name‑server pattern. Because the domain leverages a reputable TLS certificate, reliance on certificate trust alone is insufficient; correlation with brand‑impersonation tags and the observed page title should be incorporated into detection logic.
