Resumen de las pruebas
The domain extension-coin-base.pages.dev was registered on February 21, 2026 through Cloudflare, Inc., and is hosted on Cloudflare’s edge network (AS13335) with the IP address 172.66.47.151 located in the United States. The site presents a TLS certificate issued by Google Trust Services under the WE1 label, and the HTTP response returns a 403 status code. Infrastructure fingerprints show the presence of HSTS, Cloudflare reverse‑proxy services, and HTTP/3 support, consistent with a typical Cloudflare‑protected site. The page title returned by the server is "Suspected phishing site | Cloudflare," indicating that Cloudflare has already flagged the content as malicious.
Reputation services assign extremely low scores: Gridinsoft rates the domain 0 / 100, Scamadviser 1 / 100, and VirusTotal reports that 13 of 93 scanning engines flag the domain as malicious. Google Safe Browsing tags the site for social engineering, and it appears on a single security blocklist, currently blocked by PhishDestroy. The domain is explicitly listed as impersonating the cryptocurrency exchange brand Coinbase, and the scam classification is recorded as a crypto‑related scam.
While the site is presently offline, the combination of a recent registration, low trust scores, confirmed brand impersonation, and multiple vendor detections suggests a high‑risk credential‑harvesting or fund‑theft operation targeting Coinbase users. Defenders should continue to block the domain at network perimeter devices, update web‑filtering and DNS‑sinkhole lists, and monitor for any resurgence of the domain or related sub‑domains. Analysts should also audit related traffic for attempts to contact the IP address or resolve the same nameservers (courtney.ns.cloudflare.com, keanu.ns.cloudflare.com) and correlate any user reports of unexpected Coinbase login prompts with this indicator.
