Analysis of sophussdt.com indicates a brand‑impersonation campaign targeting UPS that is currently offline but retains a measurable threat profile. The domain was registered on October 2, 2025 through Dominet (HK) Limited and resolves to the Cloudflare edge address 104.21.7.58, associated with ASN 13335 in the United States. Cloudflare services, including HTTP/3, are in use and the site presented an HTTP 400 response code, suggesting a malformed request handling or intentional error page. The SSL certificate is issued by Google Trust Services under the WE1 identifier, confirming the use of a valid TLS chain.

The page title returned by the server is “SOPH”, providing limited insight into the content; no further page analysis is available. Six of ninety‑three VirusTotal security vendors flagged the domain, and it appears in a single AlienVault OTX pulse, indicating modest detection across threat‑intel feeds. The domain is listed on one public blocklist and has been blocked by PhishDestroy, reflecting active mitigation by at least one anti‑phishing service.

Nameservers maxine.ns.cloudflare.com and zeus.ns.cloudflare.com confirm the reliance on Cloudflare’s DNS infrastructure. Defenders should add sophussdt.com to domain blocklists, monitor for any re‑activation or similar aliases, and ensure that email and web filters reference the observed indicators, including the IP address 104.21.7.58, the Cloudflare nameservers, and the Google Trust Services certificate fingerprint. Continuous reconnaissance is advised to detect any evolution of the campaign, especially if new content or additional infrastructure components appear.
