Introduction
Downloading a fake MetaMask extension is one of the fastest ways to lose your crypto. Many users install what looks like the official extension, only to discover later that their wallet has been completely drained.
These fake extensions often appear in search results, ads, or unofficial websites—and they are designed to steal recovery phrases and private data.
This guide explains how MetaMask fake extension scams work, how to identify them, and how to protect your wallet step by step.
Quick Answer
Fake MetaMask extension scams usually:
- Imitate the official MetaMask extension
- Ask for your recovery phrase
- Capture private wallet data
- Drain funds shortly after setup
The real MetaMask extension never asks for your recovery phrase after initial setup.
How Fake MetaMask Extensions Work
Fake Websites and Ads
Scammers create:
- Fake MetaMask websites
- Sponsored ads in search engines
- Look-alike domains with small spelling changes
These sites link to malicious extensions.
Fake Browser Extensions
Malicious extensions:
- Copy MetaMask’s design
- Use similar names and icons
- Appear legitimate at first glance
Once installed, they behave like the real wallet.
Recovery Phrase Theft
Victims are prompted to:
- Import an existing wallet
- Enter their recovery phrase
Once entered, scammers gain full control.
Warning Signs of a Fake MetaMask Extension 🚨
- Download links outside metamask.io
- Requests for recovery phrase unexpectedly
- Poor grammar or strange permissions
- Too many ads or pop-ups
- Recently created extensions with few reviews
The official MetaMask extension is well-established and verified.
What to Do If You Installed a Fake MetaMask Extension
Step 1: Disconnect Your Wallet Immediately
- Close the browser
- Disconnect from all DApps
- Do not enter any information
Step 2: Move Funds to a New Wallet
If your wallet may be compromised:
- Create a new wallet on a clean device
- Transfer remaining funds immediately
- Never reuse the compromised wallet
Step 3: Remove the Fake Extension
- Uninstall the extension
- Clear browser cache
- Remove unknown extensions
Step 4: Secure Your Device
- Run a malware scan

- Consider using a different browser
What NOT to Do ❌
- Do not trust “extension recovery” services
- Do not reinstall and reuse the same wallet

- Do not assume funds are safe after uninstalling
Once a phrase is exposed, the wallet is compromised.
