app-openseas[.]pages[.]dev

On 25 July 2026 analysts observed the domain app-openseas.pages.dev, registered via Cloudflare on 21 February 2026. DNS resolution points to the IPv4 address 188.114.97.3, which belongs to AS13335 Cloudflare, Inc. and is geolocated to the United States. The web server returns HTTP 403 and presents the Cloudflare‑generated page titled “Suspected phishing site | Cloudflare”. TLS termination is provided by a Google Trust Services certificate (WE1), indicating use of Cloudflare’s SSL proxy. Detected web technologies include HTTP/3, HSTS, and the Cloudflare edge platform; the authoritative nameservers are lilyana.ns.cloudflare.com and maciej.ns.cloudflare.com.

Reputation metrics show a Gridinsoft trust score of 0 / 100 and the domain appears on one security blocklist. VirusTotal analysis recorded nine positive detections out of ninety‑three scanning engines, and Google Safe Browsing classifies the site as a social‑engineering threat. PhishDestroy has also listed the domain as blocked. The observed scam type is identified as a crypto scam, and the domain is explicitly associated with brand impersonation of OpenSea. The evidence confirms that the infrastructure is fully hosted on Cloudflare and that the site has already been taken offline.

However, the underlying intent—whether to harvest credentials, lure cryptocurrency transactions, or perform another malicious action—cannot be confirmed from the available data because the page content beyond the Cloudflare warning was not captured. Defenders should continue to monitor DNS queries for app-openseas.pages.dev and related subdomains, enforce outbound filtering for connections to the IP 188.114.97.3, and include the domain in threat‑intel feeds that track OpenSea‑related impersonation. Organizations using OpenSea services should advise users to verify URLs and consult official channels before entering any credentials or cryptocurrency information.
