If you suspect that your MetaMask wallet has been compromised, it’s crucial to act quickly to protect your assets. Follow these steps to secure your wallet and minimize potential losses.

1. Disconnect from the Internet

If you believe your wallet has been compromised, immediately disconnect your device from the internet:

  • This can prevent further unauthorized access to your wallet.
  • Disable Wi-Fi and unplug any Ethernet cables.

2. Change Your Password

If you can still access your MetaMask wallet, change your password immediately:

  • Go to the MetaMask settings and update your password to a strong, unique one.
  • Ensure that your new password is different from the previous one.

3. Secure Your Seed Phrase

If you suspect a compromise, consider your seed phrase at risk:

  • Do not share your seed phrase with anyone.
  • Write it down and store it securely offline if you haven't already.
  • Consider generating a new wallet and transferring your assets.

4. Create a New Wallet

To protect your assets, create a new MetaMask wallet:

  1. Open MetaMask and click on the account icon.
  2. Select "Create Account" to generate a new wallet.
  3. Set a strong password and securely store the new seed phrase.

5. Transfer Your Assets

Once your new wallet is set up, transfer your assets from the compromised wallet:

  • Access your old wallet and initiate transfers to your new wallet.
  • Be cautious and double-check the address to avoid mistakes.

6. Monitor Your Accounts

After transferring your assets, keep an eye on your accounts:

  • Check for any unauthorized transactions.
  • Set up alerts for your new wallet if possible.

7. Report the Incident

If you believe your wallet was compromised due to a phishing attack or other malicious activity:

  • Report the incident to MetaMask support.
  • Notify your contacts to warn them of potential phishing attempts.

8. Review Security Practices

After resolving the situation, review your security practices:

  • Ensure you are following best practices for wallet security.
  • Consider using a hardware wallet for added security.

9. Conclusion

Acting quickly and decisively can help you mitigate losses if you suspect your MetaMask wallet has been compromised. By following these steps, you can secure your assets and enhance your wallet's security for the future.
