“jupfn.com | 522: Connection timed out”
Resumo das evidências
The domain jupfn.com was registered on 21 February 2026 through Dominet (HK) Limited and is currently active. It appears on one public security blocklist and has been flagged by PhishDestroy. The site returns an HTTP 521 response and the page title observed is “jupfn.com | 522: Connection timed out”, indicating that the origin server is not responding through Cloudflare’s edge network. Technical resolution shows jupfn.com resolving to the IP address 188.114.96.3, which belongs to AS13335 Cloudflare, Inc. in the United States. The domain is served by Cloudflare with HTTP/3 enabled and presents an SSL certificate issued by Google Trust Services / WE1. Nameserver delegation points to bradley.ns.cloudflare.com and surina.ns.cloudflare.com, confirming full reliance on Cloudflare’s infrastructure. Threat intelligence signals a high risk classification. Two out of ninety‑five VirusTotal scanners have flagged the domain, and Gridinsoft assigns a trust score of 0 out of 100, suggesting malicious intent. The combination of a recent registration, low trust score, blocklist presence, and the inability of the origin server to deliver content (HTTP 521/522) aligns with typical credential‑harvesting setups that use Cloudflare to hide the true backend. Defenders should immediately block outbound connections to 188.114.96.3 and add jupfn.com to DNS filtering policies. Continuous monitoring of DNS queries for this domain is advised, as the underlying backend may become active at any time. Incident response teams should also consider sinkholing the domain via Cloudflare if possible, and investigate any recent authentication attempts that may have been directed to this host.
