en-opense[.]pages[.]dev

On 23 July 2026 the domain en-opense.pages.dev was observed hosting a site that presented the page title “Suspected phishing site | Cloudflare”. The domain was registered on 21 February 2026 through Cloudflare, Inc., and resolves to the IP address 172.66.47.7, which belongs to AS13335 Cloudflare, Inc. in the United States. The TLS certificate is issued by Google Trust Services under the WE1 label, indicating a valid HTTPS endpoint, while the server advertises HSTS, Cloudflare services and HTTP/3. Google Safe Browsing classifies the URL as a social‑engineering threat, and VirusTotal records ten detections out of ninety‑three scanning engines, confirming that multiple security products consider the domain malicious.

The site has been blocked by PhishDestroy and appears on one public security blocklist. Independent trust‑rating services assign extremely low scores (Gridinsoft 0/100, Scamadviser 1/100), reinforcing the assessment of high risk. The HTTP response returned a 403 status, suggesting that the content is not publicly accessible at the time of testing, and the domain is currently listed as offline. The primary malicious objective is identified as brand impersonation of OpenSea, as indicated by the “Impersonates: OpenSea” field.

No additional indicators of compromise, such as malicious payloads or credential‑stealing forms, have been disclosed, leaving the exact phishing workflow uncertain. Defenders should add the domain and its associated IP address to local and network‑level blocklists, monitor for any future DNS resolution changes, and ensure that endpoint protection solutions are updated with the latest Google Safe Browsing and VirusTotal signatures. Continuous observation of Cloudflare name servers (arnold.ns.cloudflare.com, reza.ns.cloudflare.com) is recommended to detect potential re‑use of the infrastructure for new impersonation campaigns.
