pro-cdn-coin-auth[.]pages[.]dev

pro-cdn-coin-auth.pages.dev was observed serving a page titled “Login to KuCoin | Trade Bitcoin, Ethereum & Altcoins” while the domain is listed as impersonating Coinbase. The domain was registered on October 08 2025 through Cloudflare, Inc., and resolves to the Cloudflare edge address 172.66.47.81 located in the United States under ASN 13335. DNS queries return the Cloudflare authoritative nameservers charles.ns.cloudflare.com and karina.ns.cloudflare.com. HTTP requests receive a 403 response, and the TLS handshake presents a certificate issued by Google Trust Services under the WE1 root, indicating a valid HTTPS configuration.

Detected technologies include HSTS, Cloudflare’s CDN, and HTTP/3 support. VirusTotal analysis shows that 15 of 95 scanning engines flagged the domain as malicious, and the domain appears on a single external blocklist. PhishDestroy has actively blocked the host, and the Gridinsoft trust score is 0 / 100, reinforcing the malicious assessment. The site is categorized as a “Crypto Scam” and is specifically marked as a brand‑impersonation attempt against Coinbase, despite the page title referencing KuCoin, suggesting a possible credential‑harvesting or redirection campaign targeting users of multiple cryptocurrency platforms.

The domain is currently offline, as indicated by the “taken offline” status, and no additional content was captured. Because the site is hosted on Cloudflare’s shared infrastructure, the IP address may be reused by unrelated legitimate services, so blocking the IP alone could cause collateral impact. Defenders should add the fully qualified domain name to URL filtering and DNS block lists, monitor for any re‑registration or similar sub‑domains, and enforce strict email and web gateway policies that detect mismatched brand references (e.g., Coinbase branding on a KuCoin‑titled page). Continuous observation of Cloudflare‑hosted IP ranges for anomalous HTTP‑403 responses associated with this domain is also advised.
