lineabuilidcheck[.]xyz

This domain is flagged for elevated risk due to brand impersonation targeting Linea, a blockchain platform. The threat involves presenting fraudulent verification or authentication pages to harvest user credentials, private keys, or other sensitive information under the guise of legitimate Linea services. Analysis indicates this domain was specifically designed to exploit trust in the Linea brand for malicious purposes. Infrastructure analysis reveals the following technical indicators: the domain lineabuilidcheck.xyz resolves to IP address 104.21.83.230 and was registered on October 28, 2023, through NiceNIC International Group Co., Limited. Security vendor detections on VirusTotal show 7/95 engines flagging the domain as malicious. The domain appears on one security blocklist and has been included in one AlienVault OTX threat intelligence pulse. Notably, the domain lacks an SSL certificate and displays the page title 'Just a moment...', a common characteristic of temporary or cloaked malicious pages. The domain is currently offline, but historical activity suggests it was operational during its brief existence. Mitigation for this brand impersonation threat requires multi-layered defenses. Network-level protections should block both the domain lineabuilidcheck.xyz and its associated IP 104.21.83.230 at firewalls and DNS resolvers. Endpoint security solutions should be configured to detect and prevent access to domains registered through NiceNIC with recent creation dates, particularly those impersonating blockchain platforms. User awareness training should emphasize verifying domain authenticity before entering credentials, especially for verification pages, and checking for valid SSL certificates. Organizations should monitor for similar domains using permutations of 'linea' and 'build' or 'check' in their naming structure, as these patterns are commonly used in brand impersonation attacks targeting the cryptocurrency sector.
