test-5cw[.]pages[.]dev

This domain, test-5cw.pages.dev, poses a direct threat as a brand impersonation site designed to deceive users of the OpenSea platform. Analysis indicates the site mimics the legitimate OpenSea interface, likely to harvest credentials or facilitate fraudulent transactions, such as unauthorized NFT transfers or cryptocurrency theft. The page title explicitly displays 'OpenSea,' reinforcing the deception, and the domain infrastructure is configured to appear authentic, including the use of HSTS and HTTP/3 protocols. Evidence supporting the malicious classification includes detection by 13 out of 95 security vendors on VirusTotal, registration through Cloudflare, Inc. on April 27, 2026, and presence on one security blocklist. The domain resolves to the IP address 188.114.97.3, which is associated with Cloudflare’s network, a common tactic to obscure hosting origins. Additionally, the SSL certificate is issued by Google Trust Services, further blending in with legitimate traffic while maintaining a Gridinsoft trust score of 0/100, indicating high risk. Users who visited test-5cw.pages.dev should immediately revoke any active sessions on OpenSea or related platforms, particularly if credentials were entered or transactions were initiated. It is recommended to scan the device for malware, as brand impersonation sites often deploy additional payloads. Monitor financial and digital asset accounts for unauthorized activity, and report the incident to the legitimate platform’s security team for further investigation. Avoid interacting with any communications or prompts originating from this domain, as they may be part of a broader phishing campaign.
