casefb354654-teaq[.]vercel[.]app

casefb354654-teaq.vercel.app was registered through Tucows Domains Inc. on 21 February 2026. The domain resolves to 216.198.79.3, an address owned by Amazon.com, Inc. (AS16509) located in the United States. HTTPS is served by a Google Trust Services certificate issued by the WR1 intermediate, indicating a valid TLS chain, and the server presents an HSTS header. When accessed, the site returned HTTP status 451 and displayed the page title “Deployment Unavailable”, which suggests that the original Vercel deployment has been taken offline. The infrastructure fingerprint shows the Vercel hosting platform, consistent with the resolver IP and the observed technologies.

Threat intelligence sources have flagged the domain as a generic phishing vector. Twelve of ninety‑three VirusTotal scanners reported detections, and the domain appears on the PhishDestroy blocklist. No additional public blocklists were noted. The limited detection count indicates that some security products have identified malicious behavior, but the majority have not flagged it, possibly due to the temporary offline state. Defenders should treat the domain as malicious until further analysis confirms otherwise.

Immediate actions include adding the host to network deny lists, updating URL filtering policies, and monitoring DNS queries for the 216.198.79.3 address. Continuous observation of the domain’s status is advised, as the “Deployment Unavailable” page may be a placeholder for a future phishing landing page. Correlating any authentication attempts or credential submissions to this host with internal logs will help determine active exploitation. Because the SSL certificate is valid and the site uses HSTS, standard TLS inspection may be required to uncover hidden payloads if the site becomes active again.
