rainbet-pl[.]eu[.]com

Analysis of the domain rainbet-pl.eu.com indicates a high-risk phishing operation targeting online betting credentials. As of July 28, 2026, the domain remains active and is flagged by three independent security blocklists, including PhishDestroy, MetaMask, and SEAL. VirusTotal reports that 4 out of 91 security vendors classify this domain as malicious, confirming its detection in automated threat intelligence feeds. The domain resolves to IP address 104.21.92.152, hosted on Cloudflare infrastructure, with nameservers igor.ns.cloudflare.com and jen.ns.cloudflare.com.

This hosting pattern is consistent with threat actors leveraging Cloudflare's CDN and proxy services to obscure origin servers and evade takedown efforts. No specific brand impersonation details or phishing kit identifiers are currently available in the observable evidence. The exact content served by the domain has not been analyzed, so the precise mechanics of credential harvesting—such as fake login forms, session token theft, or wallet-draining scripts—remain unconfirmed. However, the presence of MetaMask in the blocklist data suggests potential targeting of cryptocurrency wallet credentials, a common tactic in betting-related phishing schemes.

Defenders should treat this domain as actively hostile. Immediate actions include blocking DNS resolution to 104.21.92.152, adding the domain to web gateway and email filtering rules, and monitoring for connections from internal assets. Given Cloudflare's role in masking the true origin, sinkholing or takedown requests may require coordination with the registrar or Cloudflare's abuse team. No SSL certificate details or HTTP response codes are provided in the current intelligence, so further investigation into TLS handshake behavior and server headers is recommended to refine detection logic.
