gieminiilogin[.]gitbook[.]io

Analysis indicates that gieminiilogin.gitbook.io is an active credential phishing domain targeting users of the Gemini cryptocurrency exchange platform. The domain, created on March 30, 2014, is hosted on Cloudflare infrastructure, resolving to IP address 104.18.40.47 and utilizing Cloudflare nameservers (dahlia.ns.cloudflare.com and hugh.ns.cloudflare.com). Despite its long registration history, the domain has been flagged by multiple security vendors, appearing on two blocklists: PhishDestroy and OpenPhish. VirusTotal reports that 12 out of 91 security vendors classify this domain as malicious, reinforcing its high-risk status.

Infrastructure analysis reveals that the domain is still operational as of July 28, 2026, with no indications of takedown or mitigation. The use of GitBook’s subdomain structure suggests an attempt to leverage a legitimate documentation platform to lend credibility to the phishing campaign. However, the exact content of the site has not been analyzed, and no specific phishing kit or additional technical artifacts (e.g., SSL certificate details, HTTP response headers) are currently available in public threat feeds. Defenders should treat this domain as a confirmed phishing threat targeting Gemini credentials.

Recommended actions include blocking the domain at the DNS or proxy level, updating endpoint protection rules to flag or quarantine related activity, and alerting users to avoid interaction with the site. Organizations handling cryptocurrency transactions should prioritize monitoring for credential theft attempts linked to this domain. Further investigation into associated infrastructure, such as hosting providers or redirect chains, may uncover additional compromised or malicious resources.
