extension-coinbasa[.]pages[.]dev

The domain extension-coinbasa.pages.dev was created on February 21, 2026 and is currently taken offline. Infrastructure analysis shows the site was hosted behind Cloudflare, resolving to IP address 172.66.47.172, which belongs to AS13335 Cloudflare, Inc. in the United States. The domain uses HSTS and HTTP/3, and its SSL certificate is issued by Google Trust Services under the WE1 designation, indicating a valid TLS termination provided by Cloudflare. DNS resolution is served by the Cloudflare nameservers nucum.ns.cloudflare.com and lakas.ns.cloudflare.com.

HTTP requests to the site returned a 403 status code, and the page title presented by the server is "Suspected phishing site | Cloudflare," confirming the classification as a phishing‑related page. Reputation metrics are extremely low: Gridinsoft assigns a trust score of 0 out of 100, and Scamadviser rates the domain at 1 out of 100. The site appears on one security blocklist and has been explicitly blocked by the PhishDestroy service. VirusTotal scans recorded 14 detections out of 93 security vendors, and Google Safe Browsing flags the domain for social engineering, reinforcing the credential‑phishing assessment.

While the exact target brand or credential type is not disclosed in the available data, the combination of a Cloudflare‑protected domain, low trust scores, blocklist inclusion, and multiple security vendor detections provides strong evidence of malicious intent. Defenders should continue to block the domain at network perimeters, monitor for any re‑hosting attempts, and update endpoint and URL filtering policies to include the domain and its associated IP range. Ongoing observation is recommended to verify whether the threat actor attempts to reactivate the site or pivot to related infrastructure.
