This domain is flagged as a high-risk crypto drainer, specifically designed to siphon cryptocurrency from compromised wallet connections. Analysis indicates the site employs deceptive wallet authorization prompts to trick users into granting access, enabling unauthorized transactions and fund theft. Infrastructure analysis reveals the domain h5.bitfinn.com is registered through Chengdu Fly-Digital Technology Co., Ltd., with an anomalous creation date of May 05, 2026, suggesting possible registry manipulation or typo-squatting. It resolves to IP 103.164.63.209, hosted in Hong Kong under AS401696 (cognetcloud INC). The domain appears on 3 security blocklists and is flagged by 5 out of 95 security vendors on VirusTotal. SSL certification is provided by Let's Encrypt (R13), a common tactic among phishing sites to appear legitimate. Detection systems such as PhishDestroy, MetaMask, and SEAL have already blocked this domain. Mitigation requires immediate action from both users and network defenders. Wallet holders should revoke any suspicious connected sites via their wallet settings and verify transaction requests manually. Network-level protections should include DNS sinkholing for 103.164.63.209 and domain blocking at the firewall or proxy level. Security teams are advised to monitor for outbound connections to the IP and domain, as well as anomalous wallet authorization attempts originating from internal networks. Cryptocurrency platforms should alert users to this specific threat and reinforce multi-factor transaction verification.
