ultrabet-resmi-erisim[.]vip

The domain ultrabet-resmi-erisim.vip is identified as a credential phishing site targeting users of the Mavibet online platform. Analysis indicates the domain impersonates Mavibet, a well-known betting service, to deceive users into submitting login credentials. The site is currently offline, but prior activity suggests it operated as a fraudulent gateway under the guise of providing "Hızlı Erişim ve Akıcı Oyun Deneyimi" (Fast Access and Smooth Gaming Experience), as reflected in its page title. Infrastructure analysis reveals the domain was registered on February 21, 2026, through NiceNIC International Group Co., Limited, a registrar frequently associated with high-risk domains. It resolved to the IP address 188.114.97.3, which is part of a network range linked to multiple phishing campaigns. Detection metrics show the domain was flagged by 2 of 95 security vendors on VirusTotal, while Gridinsoft assigned it a trust score of 0 out of 100. Additionally, the domain appears on one security blocklist and was blocked by PhishDestroy. The site employed Cloudflare services, including Browser Insights and HTTP/3, alongside an SSL certificate issued by Google Trust Services, likely to lend an appearance of legitimacy. At present, ultrabet-resmi-erisim.vip is offline, though its prior operational state and registration details warrant continued monitoring. Users who may have interacted with the domain are advised to reset any credentials entered on the site, particularly those associated with Mavibet accounts. Organizations should update blocklists to include this domain and its associated IP address. Given the elevated risk level, security teams are recommended to conduct retrospective log analysis to identify potential exposure and implement multi-factor authentication as a mitigation measure against credential theft.
