ston-fi[.]web[.]app

Analysis of ston-fi.web.app shows a recently created domain (registered on February 21, 2026) that is hosted on Google Firebase infrastructure. The domain resolves to the Fastly edge address 199.36.158.100, associated with ASN 54113 in the United States. TLS is provided by Google Trust Services under the WR4 certificate, and the service enforces HSTS while supporting HTTP/3.

An HTTP request returns a 404 status code, yet the page title "Ston.fi x The Open League" is still reported, indicating that the site previously hosted content targeting the Ston.fi brand. The domain is listed on one security blocklist and is actively blocked by PhishDestroy. VirusTotal scanning recorded detections from 2 of 93 security vendors, reinforcing the suspicion of malicious activity.

The current offline status limits direct observation of the site’s payload, leaving the exact phishing vector and victim interaction unknown. Defenders should treat the domain as a confirmed phishing indicator: add the hostname to URL filtering and DNS blocklists, monitor for any future resolution changes, and enforce strict outbound controls to prevent credential submission to this endpoint. Continuous re‑evaluation is advised in case the site becomes active again or additional detections emerge.
