portal-cdp-coinbase[.]pages[.]dev

Analysis indicates that the domain portal-cdp-coinbase.pages.dev was registered on February 21 2026 through Cloudflare, Inc. and resolves to the IP address 188.114.97.3, which belongs to AS13335 Cloudflare, Inc. in the United States. The hosting infrastructure serves the site over HTTPS with a certificate issued by Google Trust Services under the WE1 designation, and the server advertises HTTP/3 and enforces HSTS, consistent with typical Cloudflare‑protected sites. The HTTP response code observed is 403, and the page title returned by the server is “Suspected phishing site | Cloudflare”, indicating that the content has been flagged by Cloudflare’s automated protection mechanisms. The domain is explicitly linked to a brand impersonation campaign targeting Coinbase, as reflected in the “Impersonates: Coinbase” tag and the classification of the activity as a “Crypto Scam”. The site was taken offline at the time of reporting, and PhishDestroy has recorded the domain as blocked.

Additional reputation data show a Gridinsoft trust score of 0 out of 100 and presence on a single security blocklist. VirusTotal analysis reports that 12 of 95 scanning engines flagged the domain, providing independent corroboration of malicious intent. Defenders should treat any traffic to portal‑cdp‑coinbase.pages.dev as hostile. Network controls should block outbound connections to the IP 188.114.97.3 and to the full domain, and DNS filtering should be applied to prevent resolution. Email gateways should be updated to flag messages that reference the domain or use similar sub‑domains of pages.dev.

Because the site is hosted on Cloudflare’s shared infrastructure, further investigation of related sub‑domains under the same nameservers (tara.ns.cloudflare.com, sterling.ns.cloudflare.com) may reveal additional phishing assets. Continuous monitoring of Cloudflare‑associated blocklists and re‑scanning with VirusTotal or comparable services is recommended to capture any re‑activation attempts.
