logn-upholde-uss[.]pages[.]dev

This domain was observed as an offline credential‑phishing site hosted on Cloudflare’s network. The domain logn-upholde-uss.pages.dev was registered on 21 February 2026 through Cloudflare, Inc.; its authoritative nameservers are nova.ns.cloudflare.com and armfazh.ns.cloudflare.com, indicating the attacker leveraged Cloudflare’s free DNS service. The site resolves to the IPv6 address 2606:4700:310c::ac42:2efd, which belongs to AS13335, Cloudflare, Inc., and the IP is geolocated in the United States. HTTP requests return status 403 and the page title presented by Cloudflare reads “Suspected phishing site | Cloudflare”, confirming that the hosting provider has already taken the site down. The site employed HSTS and HTTP/3, and the TLS certificate is issued by Google Trust Services under the WE1 brand, showing a legitimate‑looking HTTPS configuration.

Threat intelligence shows that 13 of 93 VirusTotal scanners flagged the domain as malicious, and Google Safe Browsing classifies it as a social‑engineering threat. The domain appears on one public blocklist and is listed by PhishDestroy as blocked. Gridinsoft assigned a trust score of 0 out of 100, reflecting extreme risk. The identified scam type is credential phishing, though the specific target brand or credential type has not been disclosed.

No payload samples, login form screenshots, or phishing‑kit details have been released; therefore the exact credential collection method remains unknown. Defenders should add the domain and its IPv6 address to inbound and outbound block lists, monitor DNS queries for the domain and its nameservers, and enforce strict URL filtering for Cloudflare‑hosted pages that resolve to this address. Given the low trust score and multiple vendor detections, any traffic attempting to reach the domain should be dropped. Continuous monitoring of Cloudflare‑issued certificates for similar patterns is advised.
