open-sea-logn[.]pages[.]dev

The domain open-sea-logn.pages.dev was registered on February 21, 2026 and is currently taken offline. It resolves to the Cloudflare‑owned address 172.66.47.195, located in the United States under ASN 13335 (Cloudflare, Inc.). DNS is served by the Cloudflare nameservers seamus.ns.cloudflare.com and itzel.ns.cloudflare.com, confirming the use of Cloudflare’s registration and hosting services. The site presented the page title “opensea login”, indicating an explicit attempt to impersonate the OpenSea marketplace. The classified scam type is Wallet/Seed Phishing, consistent with attempts to harvest private keys or seed phrases from users who believe they are authenticating to OpenSea.

Technical analysis shows the server responds with HTTP 403, enforces HSTS, and supports HTTP/3, all typical of Cloudflare‑protected sites. The SSL certificate is issued by Google Trust Services under the WE1 root, providing a valid TLS chain but offering no indication of legitimacy. Reputation scoring is extremely low, with Gridinsoft assigning a 0/100 trust score. VirusTotal records show that 2 of 93 scanned security vendors flagged the domain, and Google Safe Browsing categorises it as social engineering. The domain appears on a single external blocklist and has been actively blocked by the PhishDestroy service.

While the infrastructure points to a legitimate CDN provider, the combination of a deceptive page title, brand impersonation, and low trust scores strongly suggests malicious intent. Defenders should continue to block the domain at network perimeters, monitor for any resurgence of the host, and educate users about unsolicited OpenSea login prompts. Indicators such as the IP address 172.66.47.195, the specific Cloudflare nameservers, and the observed TLS certificate should be added to detection rules.
