Evidence Summary

CRITICAL

Analysis indicates that the domain s2-quant.network has been taken offline and now returns HTTP 404 for all requests. The page title returned by the server is "Google", which aligns with the SSL certificate issued by Google Trust Services under the WE1 profile. The site was registered through Cloudflare, Inc., and its authoritative name servers are brenna.ns.cloudflare.com and hassan.ns.cloudflare.com. Traffic for the domain resolves to IP address 142.251.40.164, an address owned by Google LLC (AS15169) located in the United States.

The HTTP stack advertises Cloudflare edge services and HTTP/3 support, suggesting that the infrastructure was leveraged to hide malicious hosting behind a reputable CDN. The domain is flagged as a Gmail impersonation, matching the "brand target" field, and was blocked by the PhishDestroy blocklist. VirusTotal scans show that 2 of 95 security vendors recorded detections, and the domain appears on one additional security blocklist. The SSL certificate, while legitimate for Google, does not guarantee the content of the site and may have been obtained through the registrar's default certificate provisioning.

The combination of legitimate cloud infrastructure, a generic "Google" page title, and limited vendor detections suggests a low‑volume, targeted impersonation campaign that has been disrupted. Defenders should continue to monitor DNS queries for the IP 142.251.40.164 and related Cloudflare name servers for any resurgence, enforce strict SPF/DKIM/DMARC checking for Gmail traffic, and ensure that URL filtering solutions block any resolved endpoints associated with s2-quant.network. Given the offline status, immediate remediation is limited to updating blocklists and verifying that no cached copies remain in internal proxies.
