rainbet-casino-cz.com was registered on May 26, 2026 through NameSilo, LLC. The authoritative name servers are michelle.ns.cloudflare.com and sevki.ns.cloudflare.com, indicating that the domain is fronted by Cloudflare’s CDN and DDoS mitigation service. DNS resolution returns the IPv4 address 172.67.223.128, an IP range owned by Cloudflare, which masks the true hosting location and makes attribution to a specific infrastructure difficult. A VirusTotal scan shows that four of ninety‑one security engines flagged the domain, confirming that at least a minority of scanners consider it malicious. The domain appears on three public blocklists and is actively blocked by the PhishDestroy, MetaMask, and SEAL mitigation services, suggesting that multiple anti‑phishing feeds have observed abusive activity associated with the domain.
The threat type is identified as generic phishing, but no additional context such as a specific brand impersonated, page title, or SSL certificate details has been published. Consequently, the exact content of the landing page, the credential‑capture mechanism, and any payload delivery remain unknown. Absence of public Safe Browsing or Open Threat Exchange entries further limits visibility into the broader ecosystem of related campaigns. The domain is currently marked as active with a high risk rating, indicating ongoing malicious use.
Defenders should block rainbet-casino-cz.com at the DNS or proxy level and add the IP 172.67.223.128 to network‑wide deny lists, recognizing that the IP may host multiple unrelated sites due to shared Cloudflare infrastructure. Monitoring for new entries on OTX, Google Safe Browsing, and additional blocklists is recommended, as the domain may evolve or spawn sub‑domains. Organizations should also enforce multi‑factor authentication and educate users about unsolicited requests for casino‑related credentials to mitigate potential credential‑theft attempts originating from this domain.
