证据摘要
The domain learn-upheld-login-web.pages.dev was registered on February 21, 2026 through Cloudflare, Inc. and is currently taken offline, returning an HTTP 403 response. Infrastructure analysis shows the domain resolves to IP address 172.66.44.233, which belongs to AS13335 Cloudflare, Inc. and is geolocated in the United States. The site is served over HTTPS using a certificate issued by Google Trust Services under the WE1 identifier, and the hosting stack reports HSTS and HTTP/3 support.
The page title returned by the server is "Suspected phishing site | Cloudflare," confirming that the content is being blocked by Cloudflare’s protective mechanisms. Reputation data indicates a Gridinsoft trust score of 0 out of 100, and the domain is listed on a single security blocklist, where it is actively blocked by PhishDestroy. VirusTotal analysis shows that 9 of 93 scanning vendors flagged the domain, and Google Safe Browsing classifies it as a social‑engineering threat.
The observed scam type is credential phishing, though the specific target brand or credential collection page has not been disclosed in the available data. Defenders should add the domain and its associated IP address to deny‑list rules, monitor for any re‑registration attempts, and enforce outbound filtering for traffic to Cloudflare‑hosted IP ranges that exhibit similar HTTP 403 responses. Continuous observation of the Cloudflare nameservers sierra.ns.cloudflare.com and andy.ns.cloudflare.com is advised, as changes may indicate re‑use of the infrastructure for future campaigns.
