sso-upheld--en-io[.]pages[.]dev

Analysis of sso-upheld--en-io.pages.dev shows that the domain was registered on 21 February 2026 through Cloudflare, Inc. and resolves to the Cloudflare edge IP 172.66.44.94, which is announced by AS13335 and geolocated to the United States. The site serves an HTTPS certificate issued by Google Trust Services under the WE1 intermediate, confirming that TLS termination is provided by Cloudflare’s infrastructure. HTTP requests receive a 403 response and the page title returned is “Suspected phishing site | Cloudflare”, indicating that the content has been taken offline or blocked by Cloudflare’s protective services. The domain appears on a single security blocklist and is listed by PhishDestroy as a known phishing indicator.

Google Safe Browsing classifies the URL as social engineering, and VirusTotal records 12 of 93 scanning engines flagging the domain, reinforcing the malicious assessment. Gridinsoft assigns a trust score of 0 out of 100, and the site advertises HSTS, HTTP/3, and Cloudflare technology, typical of fast‑path delivery networks used by phishing operators. The observed scam type is credential phishing, though the specific target brand is not disclosed in the collected data.

Evidence does not reveal any active payload, credential‑harvesting forms, or redirects, and the current HTTP status suggests the site is offline. Defenders should continue to block the host at the network perimeter, update URL filtering blocks with the domain and its associated IP address, and monitor for any future re‑registration of the same second‑level name under a different registrar. Correlation with other Cloudflare‑hosted phishing incidents is advisable, given the shared infrastructure, and security teams should consider adding the domain to internal threat intel feeds to improve detection of related campaigns.
