jack4fan.com was taken offline and is currently listed as blocked by PhishDestroy. The domain resolves to Cloudflare IP 104.21.72.5, which is announced by AS13335 Cloudflare, Inc. and geolocated to the United States. Its authoritative nameservers are megan.ns.cloudflare.com and merlin.ns.cloudflare.com, indicating the use of Cloudflare’s DNS service. Registration was performed through Dominet (HK) Limited on October 07, 2025, and no SSL certificate is present on the site, implying that the service was delivered over plain HTTP.

The page title observed before takedown reads "Jack4fan: Most Popular Online Crypto Casino Based on Blockchain," and the associated scam type is identified as a crypto scam employing the Gambler Scam phishing kit. Gridinsoft assigns a trust score of 0 out of 100, and the domain appears on a single security blocklist. VirusTotal analysis shows that five of ninety‑five scanning engines flagged the domain, corroborating its malicious nature. No additional intelligence such as Safe Browsing status, OTX mentions, or further detection vendor details are available.

The combination of a recent registration date, lack of TLS, reliance on a known gambling‑themed phishing kit, and low trust score suggests an opportunistic campaign targeting cryptocurrency enthusiasts. Defenders should ensure the domain is added to firewall and proxy blocklists, monitor for any residual traffic to the resolved IP, and consider extending detection rules to cover similar Cloudflare‑hosted gambling phishing kits. Continuous re‑evaluation of the associated blocklist entry is advised, as threat actors may reactivate the domain or replicate the infrastructure elsewhere.
