xdcserver-portal[.]online

This domain, xdcserver-portal.online, is flagged as a brand impersonation threat targeting Celer, a blockchain interoperability platform. Analysis indicates the site was designed to mimic legitimate Celer communications, as evidenced by the page title '1 new message,' a common social engineering tactic to prompt user interaction. The infrastructure appears to be part of a broader phishing campaign aimed at cryptocurrency users, though no specific drainer kit signatures were conclusively identified in preliminary scans.

Technical indicators reveal the domain was registered on December 20, 2025, through a major registrar, with resolution to the IP address 79.137.33.241. The domain is flagged by 3 out of 95 security vendors on a prominent threat intelligence platform, and it appears on four security blocklists. The SSL certificate is issued by a widely used certificate authority, which, while providing encryption, does not validate legitimacy. The domain was hosted on infrastructure utilizing technologies such as Bootstrap, LiteSpeed, and jQuery, which are commonly exploited in phishing sites to create convincing replicas of legitimate platforms.

As of the latest assessment, xdcserver-portal.online has been taken offline, likely due to enforcement actions or hosting provider intervention. However, the elevated risk remains due to the domain's recent creation, its presence on multiple blocklists, and the persistent threat of similar impersonation campaigns. Organizations and users are advised to monitor for related domains, update security feeds to include this indicator, and conduct retrospective analysis to identify any prior exposure. Cryptocurrency users should verify all communications through official channels and avoid interacting with unsolicited messages, particularly those prompting urgent action.
