rrf651[.]it

Analysis indicates that rrf651.it resolves to 104.21.12.147, an address owned by Cloudflare (AS13335) located in the United States. The domain was registered on June 16 2025 through the registrar 1 Api GmbH and is currently served from Cloudflare’s edge network, as reflected by the presence of the Cloudflare nameservers celeste.ns.cloudflare.com and kyrie.ns.cloudflare.com. The TLS certificate presented is issued by Google Trust Services under the WE1 root, confirming that HTTPS is correctly terminated. HTTP/3 support is detected, consistent with Cloudflare’s modern edge configuration.

Two of ninety‑five VirusTotal scanners flagged the domain, and the site appears on a single external blocklist. PhishDestroy has also listed the domain as malicious, and the page title returned by HTTP requests is “Welcome aboard”. No additional page content has been captured, and the site has been taken offline as of the reporting date. The limited observable footprint—namely the domain age, registration details, hosting under Cloudflare, and modest detection count—suggests a short‑lived phishing infrastructure that likely relied on the reputable Cloudflare badge to gain trust.

Defenders should add the IP address 104.21.12.147 to network block lists, enforce DNS filtering for rrf651.it, and monitor for any re‑registration of the domain or similar look‑alike domains using the same registrar or Cloudflare nameservers. Continuous querying of VirusTotal and other reputation services is recommended to capture any future detections. Because the site is currently offline, active mitigation focuses on preventive blocking and telemetry collection rather than takedown.
