No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- Domain registered: 2026-04-10 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-04-10 16:21:24 UTC (by PhishDestroy tracker) Last verified: 2026-04-21 16:09:57 UTC Neutralised: 2026-04-11 18:22:37 UTC Current status: ACTIVE — cloaked behind HTTP 666 to evade scanners ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019d778c-ad56-7066-9f44-36f205ea8afe/ Wayback Machine: https://web.archive.org/web/*/coinbasuiuextension.gitbook.io crt.sh CT logs: https://crt.sh/?q=%25.coinbasuiuextension.gitbook.io Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=coinbasuiuextension.gitbook.io AlienVault OTX: https://otx.alienvault.com/indicator/domain/coinbasuiuextension.gitbook.io URLhaus: https://urlhaus.abuse.ch/host/coinbasuiuextension.gitbook.io/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-04-10 16:22:04 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] PhishDestroy identifies a fraudulent domain posing as Coinbase’s official browser extension download page. This imposter site, coinbasuiuextension.gitbook.io, is designed to trick users into entering their cryptocurrency wallet credentials by masquerading as a legitimate service. The threat is particularly insidious because it exploits the trust users place in Coinbase’s brand while remaining undetected by most security tools. With 0 detections out of 95 VirusTotal scans, the domain evades immediate recognition as malicious, increasing the risk of successful credential theft. Users interacting with this site may unknowingly surrender sensitive login details to threat actors, potentially leading to unauthorized access and financial loss. This domain was flagged by PhishDestroy due to its clear intent to impersonate Coinbase, a leading cryptocurrency exchange. The GitBook.io subdomain (coinbasuiuextension.gitbook.io) raises red flags as Coinbase does not host official extensions or services on this domain. Technical indicators reveal the domain was created on March 30, 2014, and is registered through Cloudflare, Inc., which is often used by threat actors to conceal their true identity behind proxy services. The domain resolves to IP 172.64.147.209, a Cloudflare IP address, further masking the threat actor’s infrastructure. While the SSL certificate is issued by Google Trust Services (legitimate), this alone does not confirm the site’s safety, as threat actors frequently abuse trusted certificates to appear legitimate. If you visited coinbasuiuextension.gitbook.io, assume your credentials may have been compromised. Immediately log in to your Coinbase account and enable two-factor authentication if you haven’t already. Change your password and review recent transactions for any unauthorized activity. If you entered sensitive information, contact Coinbase support immediately to secure your account. Avoid downloading any extensions or files from this domain in the future, and report the site to your browser’s security team or PhishDestroy’s threat intelligence platform. Educate colleagues or family members about this specific imposter domain to prevent further exposure, as this threat remains active and undetected by many security solutions. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: 875a842c2da0b4c5f5ea2bf23d56f8f8 TLS cert SHA-256: e4c88edd4daf02e90c07844abf2ae51ff5c2e9f05f3f9cb09c27fc9ea634fa42 ## SCORING METHODOLOGY ---------------------------------------------------------------- Composite score is NOT derived from VirusTotal alone. PhishDestroy aggregates: - VirusTotal positive ratio - Public blocklist consensus (MetaMask, ScamSniffer, OpenPhish, PhishTank, URLhaus, CryptoFirewall, SEAL, Polkadot, Enkrypt, Phishunt, DiscordPhishing, PhishingDB) - Cloaking detection (HTTP 666 or rendering delta between bot and real visitor) - DNS-filter consensus (Quad9, CleanBrowsing, NextDNS, AdGuard, Cloudflare, etc.) - AlienVault OTX pulses + Cloudflare Radar + Google Safe Browsing - URLScan / URLQuery verdicts - Brand-impersonation heuristics (DOM analysis of forms, logos, wording) - Known phishing-kit fingerprinting (favicon hash, JS obfuscation signatures) - Wallet-drainer family classification (Angel, MS, Rainbow, Pink, Inferno, ...) - Free-TLS vs paid-cert ratio (throwaway infrastructure signal) - Registrar/hosting abuse history (this registrar's track record) - Human researcher sign-off (volunteer takedown team) A domain present in our database is ALREADY flagged. A low VT count by itself does NOT mean the domain is safe — new scam domains routinely show 0/95 VT for their first 7–30 days while actively draining wallets. Always cross-reference the composite score and the individual indicators above, not just VT. ## CORRECTIONS / APPEALS ---------------------------------------------------------------- Full HTML report: https://phishdestroy.io/domain/coinbasuiuextension.gitbook.io/ JSON API: https://api.destroy.tools/v1/check?domain=coinbasuiuextension.gitbook.io Appeal a flag: https://phishdestroy.io/appeals/ (responded to within 48 hours, FP rate <0.01%) Submit a report: https://t.me/PhishDestroy_bot About PhishDestroy: volunteer-driven open-source threat-intelligence platform.
