“Suspected phishing site | Cloudflare”
On February 21, 2026 the domain en-us-guide-coinbase-com.pages.dev was registered through Cloudflare, Inc. The authoritative nameservers are jack.ns.cloudflare.com and aleena.ns.cloudflare.com, indicating the use of Cloudflare’s DNS service. DNS resolution points to IP address 172.66.46.230, which belongs to AS13335 Cloudflare, Inc., located in the United States. An HTTPS connection is served with a certificate issued by Google Trust Services under the WE1 label, and the site enforces HSTS while supporting HTTP/3, confirming modern Cloudflare infrastructure. The page title returned by the server is "Suspected phishing site | Cloudflare" and the HTTP response code is 403, suggesting the page is currently inaccessible.
Google Safe Browsing classifies the domain as a social‑engineering threat, and VirusTotal records 12 detections out of 93 scanning engines, reinforcing the malicious assessment. Gridinsoft assigns a trust score of 0 out of 100, and the domain is listed on at least one security blocklist, with PhishDestroy confirming it as offline. The site is explicitly flagged as a crypto‑scam that impersonates the Coinbase brand.
While the exact payload or credential‑stealing mechanisms have not been observed, the combination of brand impersonation, low trust score, Safe Browsing flag, and multiple vendor detections provides strong evidence of malicious intent. Defenders should block the domain at DNS and proxy layers, add the IP 172.66.46.230 to deny lists, and monitor for any related Cloudflare‑hosted subdomains that may appear. Continuous re‑evaluation is advised in case the site is re‑hosted or the certificate is renewed, as the underlying infrastructure can be reused for future campaigns.
