us-coinbase[.]gitbook[.]io

PhishDestroy identifies us-coinbase.gitbook.io as a brand impersonation domain targeting Coinbase users. This site leverages GitBook’s legitimate platform to host a fraudulent interface designed to harvest login credentials and cryptocurrency wallet details. The threat actor employs a drainer script—likely a clipboard manipulator or web form collector—to siphon sensitive information under the guise of a Coinbase-branded service.

us-coinbase.gitbook.io exhibits multiple red flags across technical indicators. The domain resolves to IP 104.18.40.47, was registered on March 30, 2014, and uses a Google Trust Services SSL certificate. Security vendor analysis via VirusTotal reveals 11 of 95 engines flagged the site as malicious. It is hosted through Cloudflare, Inc., and appears on 2 security blocklists, including detection by MetaMask and SEAL. Despite the age of the domain, its abuse pattern aligns with modern phishing campaigns.

As of the latest assessment, the domain remains active and unblocked by major browsers. Response actions include flagging by MetaMask, SEAL, and participation in multiple blocklists, yet it continues to evade full takedown due to Cloudflare’s hosting protections. While elevated, the risk is mitigated by widespread detection and user awareness tools. Users are strongly advised to avoid interacting with this domain, verify URLs via official Coinbase channels, and report any suspicious activity to their security providers.
