trezormainnet-server[.]online

This domain is flagged as a high-risk brand impersonation threat specifically designed to impersonate Trezor, a cryptocurrency hardware wallet provider. Analysis indicates the site operates as a crypto drainer, tricking users into connecting wallets to malicious smart contracts that siphon funds without authorization. The threat vector leverages brand trust to execute financial theft through deceptive web interfaces mimicking legitimate services. Infrastructure analysis reveals the domain trezormainnet-server.online was registered on March 12, 2026, through Atak Domain, a registrar frequently associated with malicious activity. It resolves to IP address 79.137.33.241, hosted on OVH SAS infrastructure (AS16276) in France. The SSL certificate is issued by R12, a low-trust certificate authority often used in phishing campaigns. VirusTotal detection shows 19 out of 95 security vendors flag the domain as malicious, with specific classifications including crypto drainer and brand impersonation. The domain appears on three security blocklists and is actively blocked by multiple wallet protection systems. The page title 'Trezor Livemainnet' further confirms the intent to mimic Trezor's legitimate interface. Mitigation requires immediate action from both users and security teams. Users who interacted with this domain should revoke all connected wallet permissions, transfer remaining assets to a new wallet, and monitor transaction history for unauthorized activity. Security teams should implement DNS-level blocking for the domain and associated IP address, update endpoint protection rules to detect the SSL certificate fingerprint, and deploy browser-based wallet protection mechanisms to prevent connection to malicious smart contracts. Organizations should also monitor for similar domains registered through Atak Domain or hosted on OVH infrastructure, particularly those using R12 certificates and targeting cryptocurrency brands.
