coin-base-extantion-eng[.]pages[.]dev

The domain coin-base-extantion-eng.pages.dev was registered on February 21, 2026 and is currently taken offline. Infrastructure analysis shows the domain resolves to the IP address 172.66.44.65, which belongs to AS13335 Cloudflare, Inc., placing the host in the United States. Both authoritative nameservers, vera.ns.cloudflare.com and alec.ns.cloudflare.com, are Cloudflare‑controlled, confirming that the domain is hosted behind Cloudflare’s edge network. The SSL certificate presented is issued by Google Trust Services under the WE1 designation, indicating a valid TLS handshake but offering no assurance about the underlying content. HTTP probing returned a 403 status code, and the page title reported by the server is "Suspected phishing site | Cloudflare," suggesting that the site was flagged by Cloudflare’s own abuse mechanisms.

Reputation signals are strongly negative. Google Safe Browsing categorises the domain as a social engineering threat, and the independent blocklist PhishDestroy has already blocked it. VirusTotal analysis shows that 14 of 93 scanning engines have flagged the domain, reinforcing the malicious assessment. Additional rating from Gridinsoft assigns a trust score of 0 out of 100, and the domain appears on at least one external security blocklist. Detected technologies include HSTS, HTTP/3, and standard Cloudflare services, which are typical for many legitimate sites and therefore do not mitigate the observed risk.

The domain explicitly impersonates the cryptocurrency exchange brand Coinbase and is classified as a crypto‑related scam. No further content details are available because the site is offline, leaving the exact phishing payload or credential‑collection mechanisms unverified. Defenders should continue to block any traffic to the domain at network perimeters, update internal blocklists with the observed IP and hostnames, and monitor for any resurgence of the domain or related aliases.
