doc-io-trezur-start[.]pages[.]dev

Analysis of doc-io-trezur-start.pages.dev shows a credential‑phishing operation that has been taken offline. The domain was registered on 21 February 2026 through Cloudflare, Inc. and is hosted on Cloudflare’s network (ASN 13335) with the IP address 172.66.47.153 located in the United States. DNS is served by lloyd.ns.cloudflare.com and jessica.ns.cloudflare.com, both Cloudflare‑controlled name servers. The site presented the page title “Suspected phishing site | Cloudflare” and returned an HTTP 403 response, indicating that the server is actively denying normal requests. TLS termination is provided by a Google Trust Services certificate (WE1), and the connection enforces HSTS while supporting HTTP/3, confirming a modern Cloudflare edge configuration.

Reputation signals are strongly negative: Gridinsoft assigned a trust score of 0 / 100, the domain appears on one security blocklist, and PhishDestroy has explicitly blocked it. VirusTotal analysis recorded detections by three of ninety‑three scanning engines, reinforcing the malicious classification. The only publicly disclosed scam type is “Credential Phishing,” but no additional payload or landing‑page details are available because the site is currently offline. Uncertainty remains regarding the specific credential targets, the phishing kit employed, and whether any active victim data exfiltration occurred before takedown.

Defenders should continue to block the domain at perimeter firewalls, proxy filters, and DNS resolvers. Adding the domain’s IP address and its Cloudflare name‑server pair to threat‑intel feeds will help catch any future re‑hosting attempts. Monitoring for similar newly registered domains that resolve to the same Cloudflare edge IPs or that use the same name‑servers can provide early warning of related campaigns.
