secretum[.]io

This domain, secretum.io, was registered on May 15, 2026, and is currently flagged as an active credential phishing threat. Analysis indicates the domain resolves to 76.223.67.189, an IP address associated with a global content delivery network, which is a common tactic to obscure hosting origins and evade geofencing restrictions. The domain returns an HTTP 200 status, suggesting it is actively serving content, and has been blocked by at least two security blocklists, including enterprise-grade filtering systems. Additionally, the domain appears in three threat intelligence pulses, reinforcing its classification as malicious infrastructure. The SSL certificate, issued by a widely used certificate authority, does not provide meaningful trust indicators, as phishing domains routinely use valid certificates to appear legitimate. While five security vendors on a multi-engine scanning platform have flagged the domain, the specific nature of the phishing campaign remains unclear. There is no confirmed brand impersonation or phishing kit attribution at this time, though the domain name itself may imply a theme of secrecy or exclusivity to lure targets. The infrastructure analysis reveals no unusual registration patterns, but the use of a content delivery network IP and the domain's presence on multiple blocklists align with known phishing operational tactics. Defenders should treat this domain as high-risk and implement immediate blocking at the DNS and web proxy layers. Network traffic to 76.223.67.189 should be monitored for connections originating from internal hosts, as this may indicate successful phishing attempts or ongoing credential harvesting. Given the domain's recent registration and active status, it is likely part of a short-lived campaign, and defenders should prioritize retrospective log analysis to identify any prior exposure. No legitimate use case for this domain has been identified, and its continued operation suggests it remains a viable threat.
