coinbase-sing-in[.]pages[.]dev

The domain coinbase-sing-in.pages.dev was created on 21 February 2026 and is registered through Cloudflare, Inc., using the Cloudflare nameservers brady.ns.cloudflare.com and mina.ns.cloudflare.com. DNS resolution points to the IP address 172.66.44.161, which belongs to AS13335 Cloudflare, Inc., and is geolocated in the United States. The site served an HTTP 403 response and the page title returned by the server was "Suspected phishing site | Cloudflare," indicating that Cloudflare’s protective service actively blocked access. The TLS certificate presented is issued by Google Trust Services under the WE1 identifier, and transport-layer security features such as HSTS and HTTP/3 are observed, both typical of Cloudflare‑protected sites.

VirusTotal analysis recorded 13 positive detections out of 95 participating security vendors, reinforcing the malicious assessment. Independent reputation services assign extremely low confidence scores: Gridinsoft rates the domain 0 out of 100, while Scamadviser reports a 10 out of 100 trust score. The domain appears on a single security blocklist and has been explicitly blocked by the PhishDestroy feed. Classification tags identify the operation as a crypto‑related scam impersonating the Coinbase brand.

Current operational status is offline, and the domain is no longer reachable. Nonetheless, the infrastructure—particularly the use of Cloudflare’s edge network and the same nameserver pair—suggests that future campaigns could be launched from similarly configured domains. Defenders should ensure that the domain is added to local deny lists, monitor for new registrations that reuse the "coinbase‑sing‑in" pattern, and watch for additional assets resolved to the same Cloudflare IP range. Continuous threat‑intel feeds should be consulted for emerging indicators tied to the observed nameservers or the 172.66.44.161 address.
