user-connect-multichain[.]cc

This domain, user-connect-multichain.cc, was registered through NiceNIC International Group Co., Limited on 25 September 2025. It resolves to the Cloudflare‑owned address 172.67.132.40, which is announced by ASN 13335 and geolocated to the United States. The hosting infrastructure is protected by Cloudflare, as indicated by the presence of Cloudflare nameservers (burt.ns.cloudflare.com and ophelia.ns.cloudflare.com) and the detection of HTTP/3 support. An HTTPS endpoint is served with a certificate issued by Google Trust Services under the WE1 intermediate, confirming that TLS termination is performed by Cloudflare’s edge. When queried, the web server returns HTTP status 521, a Cloudflare‑specific error indicating that the origin server is refusing connections.

The only visible HTML element is a page title reading “Website Created”, which provides no further functional content. The domain is listed on a single security blocklist and has been flagged by PhishDestroy, confirming that at least one anti‑phishing feed has classified it as malicious. VirusTotal analysis shows that five out of ninety‑five scanned security vendors have generated a detection for the domain, reinforcing the suspicion. The domain explicitly targets the brand “celer”, suggesting a brand‑impersonation campaign aimed at deceiving users who trust the legitimate Celer services.

No additional technical artifacts such as malicious payloads, credential‑harvesting forms, or redirect chains have been observed in the limited data set, leaving the exact attack vector uncertain. Defenders should block DNS resolution to 172.67.132.40 for the domain, enforce URL filtering based on the full hostname, and monitor outbound traffic for any attempts to contact the domain. Because the site is hosted behind Cloudflare, traditional sink‑hole techniques are ineffective; instead, threat‑intel feeds that include the domain should be integrated into endpoint and gateway controls.
