cas5x[.]com

This domain, cas5x.com, was observed hosting a counterfeit cryptocurrency casino front that claims to be the "Most Popular Online Crypto Casino Based on Blockchain". The site resolved to IP 104.21.71.91, which belongs to Cloudflare, Inc. (AS13335) and is geolocated to the United States. WHOIS records show the domain was created on 12 December 2025 and registered through MAT BAO CORPORATION, with authoritative name servers ben.ns.cloudflare.com and mina.ns.cloudflare.com. No TLS certificate was presented, indicating the site operated without HTTPS protection. VirusTotal scans reported 15 detections out of 93 security vendors, and the domain appears on at least one public blocklist.

PhishDestroy has already added the domain to its block list, and its Scamadviser trust score is 41 out of 100 while Gridinsoft assigns a score of 0 out of 100, both reflecting a high likelihood of malicious intent. The identified phishing kit is the Gambler Scam, consistent with the crypto‑casino narrative. The current status is offline, suggesting that the hosting has been taken down or the site is otherwise inaccessible. Evidence confirms that the infrastructure is typical of CDN‑based phishing operations, but the absence of an SSL certificate and low trust scores suggest limited investment in persistence.

Uncertainty remains regarding the extent of credential harvesting or financial loss, as no victim reports are publicly linked to this domain. Defenders should continue to block the IP address 104.21.71.91, add cas5x.com to URL filtering and DNS sinkhole lists, and monitor for any re‑registration attempts. Organizations that have exposed credentials to cryptocurrency services should be alerted to the possibility of credential reuse on this site. Ongoing telemetry collection from security vendors and blocklist feeds is recommended to detect any resurgence.
