chrome-extension-coinbase-us[.]pages[.]dev

Analysis of the domain chrome-extension-coinbase-us.pages.dev indicates a crypto scam operation impersonating Coinbase, classified as brand impersonation with an elevated risk level. The domain, registered on February 21, 2026, was hosted on Cloudflare infrastructure (AS13335) and resolved to the IP address 172.66.47.150, located in the United States. Nameservers zariyah.ns.cloudflare.com and amit.ns.cloudflare.com were associated with the domain, and technologies such as HSTS, Cloudflare, and HTTP/3 were detected. The SSL certificate was issued by Google Trust Services (WE1), a common provider for legitimate and malicious domains alike.

The domain was flagged by one security vendor on VirusTotal and appeared on a single security blocklist, specifically PhishDestroy. Google Safe Browsing classified the domain as engaging in social engineering, aligning with the observed scam type. The HTTP status returned was 451, accompanied by the page title 'Unavailable For Legal Reasons,' suggesting the site was taken offline due to legal or policy violations. As of the report date, the domain is offline, though historical infrastructure analysis reveals its prior use in crypto-related fraud.

Defenders should treat this domain as part of a broader pattern of Coinbase impersonation, particularly given the use of a Cloudflare Pages subdomain, which is frequently exploited for low-cost, disposable phishing infrastructure. The combination of a 451 status and legal-related page title may indicate enforcement action, but residual risk remains due to the domain's prior malicious activity. Monitoring for re-registration or similar subdomains under Cloudflare Pages is recommended, as this tactic is commonly reused in phishing campaigns targeting cryptocurrency users.
