kucoinsignin-application[.]webflow[.]io

Analysis as of July 24 2026 indicates that kucoinsignin-application.webflow.io is an active brand‑impersonation site targeting KuCoin users. The domain was created on 02 Mar 2026 and resolves to the Cloudflare address 104.18.36.248, which belongs to AS13335 in the United States. The TLS certificate is issued by Google Trust Services under the WE1 identifier, confirming the use of legitimate HTTPS infrastructure. The page title returned by the server is "KuCoin Login - Accessing Your Crypto Assets", directly matching the advertised brand target. Fingerprint data shows the site was built on Webflow and leverages jQuery, Google Hosted Libraries, Google Font API and HTTP/3 via Cloudflare’s CDN.

Gridinsoft assigns a trust score of 0 / 100, and the domain appears on one security blocklist and is blocked by PhishDestroy. VirusTotal analysis records 15 of 93 scanned security vendors flagging the domain as malicious, reinforcing the classification as a crypto scam. The HTTP response is a 404 and the current status is offline, suggesting the site has been taken down. Uncertainty remains regarding the exact content that was hosted before takedown, as no visual inspection is available.

The use of Cloudflare’s edge network can mask the true origin of the malicious operator, complicating attribution. Given the recent creation date and rapid vendor detection, the threat appears opportunistic rather than part of a long‑standing campaign. Defenders should continue to block the domain at perimeter firewalls and DNS resolvers, monitor for re‑appearance or related subdomains, and update phishing‑detection rules to include the observed page title and the Cloudflare IP range. Users should be instructed to verify KuCoin login URLs through official channels and to report any unsolicited requests for credentials.
