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.

Domain Appeal
Contest this listing if false positive
Beware of recovery scammers! After being scammed, criminals may contact you again pretending to be "recovery agents," lawyers, or investigators who claim they can retrieve your lost funds — for a fee. This is a second scam. No legitimate service will ask for upfront payment to recover stolen crypto. Learn more about recovery fraud →

Recommendations & Advice for Victims
An estimated $51 billion flowed to illicit crypto wallets in 2024 (source). If you interacted with coinbasuiuextension.gitbook.io — act now.
What should I do immediately?
Urgent
- Revoke token approvals — use revoke.cash to remove access granted to malicious smart contracts
- Move remaining funds to a brand-new wallet. The compromised wallet is no longer safe
- Change all passwords — email, exchange accounts, anything that shares the same password
- Enable 2FA using an authenticator app (not SMS). Disable SMS-based recovery
- Freeze cards if you entered banking details on the phishing site
What information should I collect for my report?
FBI guidelines
According to the FBI, the most important details are transaction data:
- Cryptocurrency addresses — scammer's wallet (e.g.,
0x5856...35985) - Amount & crypto type — exact amount (e.g., 1.02345 ETH, 0.5 BTC, 500 USDT)
- Transaction ID (hash) — the unique blockchain transaction identifier
- Exact dates & times — of each transaction and first contact with scammer
- Screenshots — scam website, chat messages, emails, wallet transactions, social media
- All URLs & domains used by the scammer (including
coinbasuiuextension.gitbook.io) - Communications — emails, texts, phone numbers, usernames the scammer used
Even if you don't have all details — file a report anyway. Partial information still helps investigations.
Where should I report the scam?
- FBI IC3 — Internet Crime Complaint Center (US federal reporting)
- Europol — European cybercrime reporting (EU)
- Chainabuse — flag scam wallets across exchanges & platforms
- Your crypto exchange — contact Coinbase/Binance/Kraken support to freeze scammer's address
- Local police — creates an official record, even if they can't act immediately
The FBI recovered over $1 billion in crypto fraud in 2024 thanks to victim reports. Your report matters.
How do crypto scams typically work?
- Fake websites — pixel-perfect clones of legitimate sites with slightly altered domains
- Malicious approvals — "connect wallet" prompts that grant unlimited token spending to attackers
- Pig butchering — trust built over weeks via Telegram/WhatsApp/dating apps, then money stolen
- Recovery scams — victims targeted AGAIN by fake "recovery agents" demanding upfront fees. Always a scam
- Fake ads & airdrops — Google/social media ads and "free token" offers leading to wallet drainers
- AI-powered scams — deepfakes, automated phishing, and AI-generated sites making fraud harder to detect
How can I protect myself in the future?
- Use a hardware wallet (Ledger, Trezor). Never store large amounts in browser wallets
- Bookmark official sites — never click links from emails, DMs, or ads
- Read every approval — verify permissions before signing. Reject unlimited approvals
- Verify domains — check on PhishDestroy before interacting. Check HTTPS, spelling, domain age
- "Too good to be true" = scam — guaranteed returns, celebrity endorsements, urgent deadlines
How big is the crypto scam problem?
- $51 billion flowed to illicit crypto wallets in 2024 — CoinLedger
- Pig butchering losses grew 40% year over year, now the fastest-growing fraud type
- Only ~5% of victims report — your report helps shut down criminal networks
- FBI recovered $1B+ in 2024 thanks to victim reports — FBI.gov
