startt---sso--kucoinn[.]webflow[.]io

The domain startt---sso--kucoinn.webflow.io is flagged as a brand impersonation site targeting KuCoin users. Infrastructure analysis shows the domain resolves to the IP address 172.64.151.8, which belongs to AS13335 operated by Cloudflare, Inc., and is geolocated in the United States. The authoritative nameservers are journey.ns.cloudflare.com and lamar.ns.cloudflare.com, confirming the use of Cloudflare DNS services. TLS termination is provided by a Google Trust Services certificate (WE1), indicating a valid SSL chain, while the site serves content over HTTP/3. The page title returned by the server is "Log In | Kucoin (Official Site)® - Sign In to Your Account™", directly referencing the KuCoin brand and suggesting a credential‑harvesting intent.

The site employs Webflow as its content management platform, a common choice for quickly deployed fraudulent pages. HTTP response code 403 was observed, and the site is currently taken offline, yet it remains listed on at least one security blocklist and has been blocked by the PhishDestroy project. VirusTotal analysis recorded 16 detections out of 93 scanned security vendors, reinforcing the malicious classification. Registration data indicates the domain was created on May 08, 2013 and is registered through MarkMonitor, Inc., a registrar often used for legitimate brand protection, highlighting potential abuse of compromised or legacy accounts.

The scam type is identified as a crypto scam, consistent with the impersonation of a cryptocurrency exchange. Defenders should continue to block the domain at network perimeter devices, update URL filtering rules, and monitor for any re‑hosting attempts on alternative infrastructure. Incident response teams should advise users to verify login URLs through official KuCoin channels and to remain vigilant for unsolicited login prompts.
