Analysis of byzantiumtrust.com, created on February 21 2026 and hosted on a Contabo Inc. server (AS40021) located in the United States, shows several indicators of compromise consistent with a high‑risk generic phishing operation. The site resolves to IP 62.146.229.150, serves content over HTTPS using a Let’s Encrypt R12 certificate, and returns HTTP 200 responses. A page title of "Home - Byzantium Trust" is observed, but no additional content has been publicly disclosed. Technological fingerprinting reveals a WordPress stack with PHP, MySQL, Nginx, Yoast SEO, and jQuery Migrate, all common components in compromised or malicious sites.

Email routing is configured to use ProtonMail MX hosts (mail.protonmail.ch with priority 10 and a secondary host with priority 20), suggesting an attempt to leverage reputable mail services for credential harvesting. The domain is registered through GoDaddy.com, LLC and uses the default GoDaddy nameservers ns53.domaincontrol.com and ns54.domaincontrol.com. Security‑monitoring services have taken action: PhishDestroy has blocked the domain, and it appears on a single security blocklist. VirusTotal reports that 1 of 93 scanning engines flagged the domain, indicating at least one detection of malicious behavior.

While the exact phishing payload or credential collection mechanism has not been disclosed, the convergence of a newly registered domain, active hosting, a legitimate‑looking SSL certificate, and detection by multiple security vendors warrants immediate defensive measures. Organizations should add byzantiumtrust.com to firewall and DNS deny lists, monitor outbound traffic for connections to the associated IP address, and enforce email authentication checks for any messages claiming to originate from the domain. Continuous observation is advised to detect any evolution of the campaign, such as the appearance of additional malicious indicators or a shift in hosting infrastructure.
