This type of cyber threat can lead to unauthorized access to personal, financial, or work-related accounts, which may result in identity theft or financial loss. Users should be cautious when interacting with this site and avoid providing any personal credentials.
PhishDestroy's analysis found that learn-extension-base-up[.]pages[.]dev currently has zero detections out of 95 antivirus engines on VirusTotal, suggesting it may be a newly emerging threat or designed to avoid detection. The domain is actively registered through Cloudflare, Inc., a well-known registrar and content delivery network, and it uses an SSL certificate issued by Google Trust Services, which could give a false sense of security. The domain resolves to IP address 188.114.97.3 and remains active, which indicates ongoing risk. The site's registration date and other historical data were not specified, but the low VT detection count and Cloudflare registration are important technical markers.
If you have visited learn-extension-base-up[.]pages[.]dev, immediately avoid entering any login or personal information. If you suspect you may have already shared credentials, change your passwords on affected accounts as soon as possible and enable two-factor authentication where available. Monitor your accounts for any suspicious activity and consider running a security scan on your devices. Avoid clicking on any links or downloading files from this domain. Staying vigilant and reporting suspicious websites to your security provider can help protect you from evolving credential theft scams.

IP is behind a large CDN (3,432+ co-hosted phishing domains on same edge IP)
The origin is proxied via Cloudflare or a similar content-delivery network. Edge-IP neighbors aren't meaningful — hundreds of unrelated customers share each edge node. Origin IP discovery requires passive-DNS or CT cross-reference.

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 learn-extension-base-up.pages.dev — 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
learn-extension-base-up.pages.dev) - 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
