The site returns an HTTP 301 redirect and presents the page title “btc-550prox.com | 523: Origin is unreachable”, indicating that the underlying landing page is intentionally unavailable to casual inspection. Infrastructure analysis shows the domain resolves to IP address 104.21.80.1, which belongs to AS13335 owned by Cloudflare, Inc. The authoritative nameservers are igor.ns.cloudflare.com and kate.ns.cloudflare.com, confirming the use of Cloudflare’s DNS and CDN services. TLS is provided by the Cloudflare TLS Issuing ECC CA 3 chain, with the certificate issued by SSL Corporation. HTTP/3 support is detected, reflecting modern protocol adoption. The domain is listed on a single security blocklist and has been flagged by PhishDestroy. VirusTotal reports a single positive detection out of 95 scanned security vendors, suggesting limited but non‑trivial awareness among scanning engines. No additional historical activity is observed beyond the initial creation date, leaving the extent of credential harvesting or monetary loss unknown. Defenders should add btc-550prox.com to network and email filtering rules, block or sinkhole the associated IP 104.21.80.1, and monitor for related Cloudflare‑hosted subdomains that may be leveraged in future campaigns. Continuous re‑evaluation of VirusTotal and blocklist status is advised, as additional detections may emerge as the campaign matures.
