unijoin[.]gold

The domain unijoin.gold is identified as a brand impersonation threat targeting Bitcoin users under the guise of a privacy service. Analysis indicates the site mimics legitimate cryptocurrency mixing platforms, presenting itself as a secure solution for Bitcoin transactions. The domain is currently offline, but prior activity suggests malicious intent to deceive users into disclosing wallet credentials or transferring funds to attacker-controlled addresses. Infrastructure analysis reveals the domain was registered through NICENIC INTERNATIONAL GROUP CO., LIMITED on May 16, 2026, an unusual future date that may indicate falsified registration details. It resolved to IP address 172.67.190.123 and employed Cloudflare services, including HTTP/3 and Browser Insights, likely to obfuscate backend infrastructure. The site was flagged by 9 of 95 security vendors on VirusTotal and appears on three security blocklists. Additional detections include entries in two AlienVault OTX threat intelligence pulses and blocking by MetaMask, PhishDestroy, and SEAL. The domain held a Let’s Encrypt SSL certificate and displayed a page title of 'UniJoin – Secure Bitcoin Privacy,' reinforcing its false legitimacy. Current status confirms the domain is offline, though historical indicators remain relevant for detection and prevention. Organizations and individuals are advised to update security controls to block the domain and associated IP address. Cryptocurrency users should verify the authenticity of any privacy service through official channels before engaging. Security teams are recommended to monitor for related domains registered under the same registrar or resolving to the same IP range, as threat actors may re-establish operations under new infrastructure.
