join-page-coinbase[.]pages[.]dev

join-page-coinbase.pages.dev was registered on February 21 2026 via Cloudflare, Inc. and resolves to the Cloudflare address 172.66.44.81, which belongs to AS13335 in the United States. The domain is hosted on Cloudflare infrastructure, indicated by the presence of HSTS, HTTP/3 and the Cloudflare‑owned nameservers ashton.ns.cloudflare.com and brenda.ns.cloudflare.com. The site presented the page title “Suspected phishing site | Cloudflare” and returned an HTTP 403 response before being taken offline. A Google Trust Services / WE1 certificate was observed, confirming the use of a valid TLS certificate but offering no assurance about the content.

VirusTotal analysis shows that 13 of 93 scanning engines flagged the domain, and the site appears on at least one public security blocklist. Independent reputation services assign extremely low trust scores (Scamadviser 1/100, Gridinsoft 0/100) and the domain has been blocked by the PhishDestroy service. The campaign is classified as a crypto‑related scam that impersonates the Coinbase brand. The combination of a recent registration date, Cloudflare‑based hosting, a valid SSL certificate, and multiple vendor detections suggests a deliberate attempt to exploit the Coinbase brand for financial gain.

Because the site is currently offline, real‑time examination of the payload is not possible, and the exact phishing page content remains unknown. Defenders should continue to block the domain at network perimeter and DNS layers, monitor for any resurgence of the host or similar sub‑domains, and update URL filtering lists with the observed indicators. Threat intelligence feeds should be enriched with the domain, its IP address, the associated nameservers, and the observed vendor detection count to aid correlation with future campaigns targeting cryptocurrency users.
