rainbetbet[.]ru

Analysis indicates that rainbetbet.ru is an active generic phishing infrastructure first observed in February 2026. The domain is registered through REGRU-RU and uses Cloudflare nameservers (emma.ns.cloudflare.com, weston.ns.cloudflare.com). It resolves to IP 188.214.30.6, which is assigned to a Romanian host (THC Projects SRL). The site presents a valid Let's Encrypt certificate (E8) and enforces HSTS while supporting HTTP/3, suggesting a modern web stack. Gridinsoft assigns a trust score of 0/100, and three of ninety‑one VirusTotal scanners flag the domain, confirming malicious intent. HTTP requests return status 200, and the page title "rainbet — поддержка и решение проблем, время ответа и верификация" is observed, but the content has not been publicly dissected. The domain appears on three security blocklists and is already blocked by PhishDestroy, MetaMask, and SEAL. An AlienVault OTX pulse references the host once, indicating limited but existing threat‑intel coverage. Uncertainties remain regarding the specific phishing kit or credential harvesting mechanisms employed, as no page‑level artifacts have been disclosed. Defenders should immediately block rainbetbet.ru and its associated IP at network perimeters, incorporate the domain into URL filtering and DNS sinkhole policies, and monitor for any related C2 activity originating from the same IP range. Continuous scanning of the host for payload delivery and periodic re‑evaluation of threat‑intel feeds are recommended to detect possible evolution of the campaign.
