rich-brain[.]ru

Analysis of the domain rich-brain.ru indicates it was operating as a financial-themed phishing platform targeting Russian-speaking users. The page title, 'krab1 - образовательная AT платформа финансового мышления,' suggests the site posed as an educational or investment training service, though the exact content and functionality remain unverified. The domain was registered on October 1, 2025, through REGRU-RU and resolved to the IP address 193.105.134.30, hosted on AS42237 (w1n ltd) in Sweden. No SSL certificate was detected, increasing the risk of unencrypted data transmission. The domain appears on one security blocklist and was flagged by PhishDestroy.

Two of 95 security vendors on VirusTotal identified the domain as malicious, though this does not confirm widespread detection. Nameservers (ns1.regerey.com, ns2.regerey.com) and the registrar (REGRU-RU) are consistent with infrastructure used in other phishing campaigns, though no direct links to known threat actor groups or phishing kits have been established. The Gridinsoft trust score of 0/100 further supports the assessment of elevated risk. As of the report date, the domain is offline, though defenders should monitor for reactivation or migration to new infrastructure.

Network defenders are advised to block the domain and its resolving IP (193.105.134.30) at the perimeter. Security teams should review logs for connections to this IP or domain, particularly from users who may have interacted with financial or educational-themed phishing lures. Additional investigation into the hosting provider (AS42237) and nameserver operator (regerey.com) may reveal related malicious domains. No brand impersonation was confirmed from the available data, but the financial focus aligns with common phishing objectives.
