Analysis indicates that the domain portal-uphold-auth-cdn.pages.dev was registered on February 21, 2026 via Cloudflare, Inc. The authoritative nameservers are simon.ns.cloudflare.com and cortney.ns.cloudflare.com, confirming the use of Cloudflare’s DNS infrastructure. DNS resolution points to the IP address 172.66.47.146, which resides within AS13335 Cloudflare, Inc., located in the United States. The site presents the page title “Suspected phishing site | Cloudflare” and serves an HTTPS certificate issued by Google Trust Services under the WE1 root, indicating a valid TLS termination provided by Cloudflare. HTTP responses return a 403 status code, and the site is presently taken offline.

Security telemetry shows that ten of ninety‑three VirusTotal scanners flagged the domain, and it is listed on a single external blocklist. The domain is also blocked by the PhishDestroy service. Additional telemetry includes the presence of HTTP Strict Transport Security (HSTS) and other Cloudflare‑specific headers. The Gridinsoft trust score of zero reinforces the malicious classification.

While the available data confirm the infrastructure and detection posture, the specific credential‑harvesting template or targeted brand is not disclosed in the collected intelligence. Consequently, defenders should treat the domain as a confirmed phishing infrastructure, enforce blocklisting at DNS and gateway layers, monitor for any resurrection or reuse of the underlying IP range, and incorporate the observed indicators (domain name, IP, SSL fingerprint, and blocklist entries) into threat‑intel feeds. Ongoing observation is recommended to capture any future activity that may reveal the intended victim brand or additional payload characteristics.
