coinbase-io-sign-en[.]pages[.]dev

coinbase-io-sign-en.pages.dev was registered on 21 February 2026 through Cloudflare, Inc. and resolves to the IP address 172.66.44.87, which belongs to AS13335 Cloudflare, Inc. and is geolocated in the United States. The domain serves an HTTPS endpoint protected by a certificate issued by Google Trust Services under the WE1 identifier, and the server advertises HTTP Strict Transport Security (HSTS) and HTTP/3, indicating a modern Cloudflare edge configuration. An HTTP request to the root URL returns a 403 status code and the page title “Suspected phishing site | Cloudflare,” which is the default block page presented by Cloudflare when it has taken down malicious content. VirusTotal scans show that 12 of 93 security vendors have flagged the domain, and the domain appears on one external blocklist that is currently enforced by PhishDestroy.

The domain’s Gridinsoft trust score is 0 out of 100, reflecting a complete lack of trust. Nameservers listed for the domain are chase.ns.cloudflare.com and alexia.ns.cloudflare.com, both Cloudflare‑controlled. The site is presently offline, suggesting that the hosting has been disabled, but the infrastructure artifacts remain indicative of a brand‑impersonation campaign targeting Coinbase users.

No further page content was retrieved, so the exact phishing vector cannot be confirmed at this time. Defenders should add the domain and its associated IP address to DNS‑based blocklists, monitor for re‑use of the IP range, and enforce outbound filtering for connections to Cloudflare‑hosted domains that are not explicitly authorized. Continuous re‑evaluation of the domain’s status is advised, as threat actors frequently re‑register similar identifiers after takedown.
