coin-base-login-fed[.]pages[.]dev

Analysis of the domain coin-base-login-fed.pages.dev indicates a high-risk brand-impersonation campaign targeting Coinbase users, first observed in February 2026. The domain was registered through Cloudflare, Inc. on February 21, 2026, and resolves to the IP address 172.66.47.171, hosted under AS13335 (Cloudflare, Inc.) in the United States. Nameservers associated with the domain include sue.ns.cloudflare.com and alfred.ns.cloudflare.com, reinforcing its Cloudflare infrastructure. Google Safe Browsing has flagged this domain for social engineering, aligning with its classification as a crypto scam. Scamadviser and Gridinsoft trust scores of 10/100 and 0/100, respectively, further corroborate its malicious intent.

The domain appears on one security blocklist, and 14 of 93 security vendors on VirusTotal have detected it as malicious. The SSL certificate is issued by Google Trust Services (WE1), a common feature in both legitimate and malicious Cloudflare-hosted sites. At the time of this report, the domain returns an HTTP 403 status, and its page title is 'Suspected phishing site | Cloudflare,' suggesting it has been taken offline or restricted by the hosting provider. Technologies detected include HSTS, Cloudflare, and HTTP/3, which are consistent with modern phishing infrastructure designed to evade detection and enhance credibility.

Defenders should treat this domain as a confirmed phishing resource targeting cryptocurrency users. The combination of brand impersonation, low trust scores, and detection by multiple security vendors warrants immediate blocking at the network and endpoint levels. Given its Cloudflare hosting, defenders may also monitor for related subdomains or newly registered domains under the same registrar. The exact content of the phishing page is not yet analysed, but the available evidence supports its classification as a crypto-focused scam impersonating Coinbase.
