en-us-opensea[.]pages[.]dev

This domain, en-us-opensea.pages.dev, poses a high-risk brand impersonation threat targeting users of the OpenSea non-fungible token marketplace. Analysis indicates the domain was designed to mimic legitimate OpenSea interfaces, likely to deceive users into connecting cryptocurrency wallets or entering sensitive credentials. The infrastructure and naming convention suggest an intent to exploit trust in the OpenSea brand, potentially leading to unauthorized asset transfers or credential harvesting. The use of a subdomain under a content delivery network further obscures the malicious origin while maintaining a superficial appearance of legitimacy. Evidence supporting this assessment includes multiple technical indicators. The domain is flagged by 11 out of 95 security vendors on VirusTotal, indicating widespread detection as malicious. It was registered on November 03, 2025, through Cloudflare, Inc., and resolves to the IP address 172.66.47.66, associated with Cloudflare’s infrastructure in the United States. The domain appears on one security blocklist, and its SSL certificate, issued by Google Trust Services, does not mitigate the underlying threat. The page title, 'Suspected phishing site | Cloudflare,' further confirms its malicious classification by automated systems. Users who visited en-us-opensea.pages.dev should take immediate action to mitigate potential risks. Those who entered credentials or connected a cryptocurrency wallet should revoke any associated permissions and transfer assets to a new wallet address. It is recommended to scan the device for malware and monitor accounts for unauthorized activity. If financial transactions were initiated, affected parties should report the incident to relevant financial institutions or blockchain analytics services. Additionally, users should verify the authenticity of any domains before interacting with them, particularly those involving financial or cryptographic operations.
