swift-guardian[.]web[.]app

Analysis of swift-guardian.web.app as of July 25, 2026 indicates that the domain is currently offline but exhibits multiple indicators of a phishing infrastructure. The domain resolves to the IP address 199.36.158.100, which is owned by Fastly, Inc. (AS54113) and located in the United States. Hosting is provided through Google’s Firebase platform, as evidenced by the detection of Firebase services, HTTP/3 support, and the presence of HTTP Strict Transport Security (HSTS). The SSL certificate is issued by Google Trust Services under the WR4 certificate profile, confirming that TLS termination is performed by Google’s certificate authority. Nameserver records point to ns-cloud.googledomains.com, and the registrar is listed as Google LLC, consistent with a domain hosted on Google Cloud infrastructure.

The HTTP response returned a 404 status code, and the only visible page title is “Welcome to our website,” which does not reveal any brand or credential‑collection intent. Nevertheless, the domain has been flagged by three of ninety‑five VirusTotal scanners, and it appears on a single external blocklist maintained by PhishDestroy. These detections suggest that security vendors have observed malicious activity linked to the domain, likely involving credential harvesting or fraudulent redirects. Given the limited public content, the precise phishing campaign details—such as the targeted brand, lure vector, or payload—remain unknown. The offline status prevents immediate verification of any active phishing page, but the presence of a valid TLS certificate, modern web protocols, and a Fastly edge location indicates that the operators have access to reputable hosting services, which can aid in evading simple reputation checks.

Defenders should continue to block swift-guardian.web.app at perimeter and DNS filtering layers, monitor for any re‑appearance of the domain or associated subdomains, and consider adding the IP address 199.36.158.100 to threat‑intel feeds.
