coinbase-chrome-extenn[.]pages[.]dev

This domain is flagged as a high-risk brand impersonation threat targeting Coinbase users. Analysis indicates the infrastructure is designed to deceive victims into disclosing login credentials, financial details, or installing malicious browser extensions under the guise of a legitimate cryptocurrency service. The threat type is classified as credential harvesting with potential secondary payload delivery, given the domain's naming convention suggesting Chrome extension spoofing. Infrastructure analysis reveals the following technical indicators: the domain coinbase-chrome-extenn.pages.dev resolves to IP address 172.66.47.60, hosted on Cloudflare's network (AS13335) in the United States. The domain was registered on November 10, 2025, through Cloudflare's registrar services. Security vendors on VirusTotal flagged this domain with 13/95 detections, while it appears on at least one security blocklist. The SSL certificate is issued by Google Trust Services (WE1), and the page title explicitly states 'Suspected phishing site | Cloudflare.' Google Safe Browsing has classified this domain as phishing, and the domain has since been taken offline, though residual risk remains for users who may have interacted with it prior to deactivation. Mitigation steps for this specific threat type include immediate credential rotation for any accounts accessed through this domain, particularly Coinbase and associated email accounts. Users should verify browser extensions for unauthorized additions, especially those claiming to be Coinbase-related. Organizations should implement domain-based blocking for coinbase-chrome-extenn.pages.dev and its resolving IP 172.66.47.60 at the network perimeter. Security teams are advised to monitor for indicators of compromise, including unusual login attempts or cryptocurrency transactions from affected accounts. Given the domain's recent creation date, additional related infrastructure may still be active, warranting enhanced vigilance for similar naming patterns (e.g., coinbase-[random].pages.dev) across monitoring systems.
