fraudulent-coinbase[.]com

The domain fraudulent-coinbase.com has been identified as a brand_impersonation threat targeting Coinbase, a major cryptocurrency exchange platform. This domain is currently offline, but prior analysis confirms its use in deceptive operations designed to mimic legitimate Coinbase services. The page title, 'Coinbase - Buy and Sell Bitcoin, Ethereum, and more with trust,' closely mirrors the official branding, increasing the likelihood of successful user deception. Infrastructure analysis reveals the domain was registered through NiceNIC International Group Co., Limited on February 21, 2026. It resolved to the IP address 104.21.72.142, hosted on AS13335 (Cloudflare, Inc.) in the United States. The domain was flagged by 17 of 95 security vendors on VirusTotal, and it appeared on two security blocklists. An SSL certificate issued by Google Trust Services (WE1) was detected, further attempting to lend an air of legitimacy to the fraudulent site. At present, fraudulent-coinbase.com has been taken offline, though the underlying infrastructure may remain accessible for future malicious campaigns. Organizations and users are advised to monitor for re-registration attempts under similar naming conventions. Blocking the domain and associated IP at the network level is recommended as a preventive measure. Additionally, users should verify domain authenticity through official channels before engaging with any cryptocurrency-related platforms.
