portal-webzoom[.]pages[.]dev

portal-webzoom.pages.dev is recorded as a brand‑impersonation site targeting Zoom. The domain was registered on 2 September 2020 through Cloudflare, Inc. and resolves to the Cloudflare‑owned address 172.66.45.36, which is mapped to the AS13335 Cloudflare network in the United States. The hosting infrastructure presents HSTS, HTTP/3 and a TLS certificate issued by Google Trust Services (WE1), indicating that the attacker leveraged reputable services to obtain a valid‑looking certificate. The HTTP response returned a 403 status code at the time of analysis, and the site is currently listed as offline, yet it remains flagged by security products.

The page title returned by the server is “Zoom”, matching the declared brand target and confirming the impersonation intent. Threat intelligence shows the domain is blocked by PhishDestroy and appears on one external blocklist. VirusTotal analysis reports three detections out of ninety‑three scanned engines, reinforcing the malicious assessment. The Gridinsoft trust score is 0 / 100, the lowest possible rating, which aligns with the observed indicators.

Nameserver configuration includes adi.ns.cloudflare.com, karl.ns.cloudflare.com, tadeo.ns.cloudflare.com and ursula.ns.c, all under Cloudflare control, further confirming the use of Cloudflare’s DNS service. While the site is no longer serving content, the combination of a brand‑specific page title, a legitimate‑looking SSL certificate, and multiple vendor detections demonstrates a clear intent to deceive Zoom users. Defenders should immediately add portal-webzoom.pages.dev to DNS‑based deny lists and web‑filter policies, monitor for new subdomains under the pages.dev namespace that reference Zoom or other collaboration services, and consider correlating any internal authentication attempts to this host with user‑reporting mechanisms. Continuous ingestion of updated blocklist feeds and periodic re‑scanning of the domain are recommended to capture any re‑activation attempts.
