How to deal with a compromised MetaMask wallet?

Immediate Steps to Take After Wallet Compromise

1. Disconnect your device from the internet to prevent further unauthorized access. This reduces the risk of additional data being transmitted to malicious actors.

2. Stop using the compromised MetaMask wallet immediately. Do not send any more funds or interact with dApps using the affected account.

3. Check recent transactions on Etherscan or a similar blockchain explorer. Identify the exact moment and method of the breach by reviewing outgoing transactions and contract interactions.

4. Revoke permissions for all smart contracts linked to the compromised wallet. Use tools like Revoke.cash to disconnect token allowances and smart contract approvals, especially for high-value tokens like USDT, DAI, or WETH.

5. Secure your recovery phrase if it was exposed. If you typed your seed phrase into a phishing site or stored it insecurely, assume it is compromised and avoid reusing it anywhere.

Recovering Access and Protecting Assets

1. Create a new MetaMask wallet with a completely new seed phrase. Ensure this is done in a secure environment, preferably on a clean device with updated software.

2. Transfer any remaining assets from the compromised wallet to the new one. Use a minimal gas fee if network congestion allows, but prioritize speed if funds are still at risk.

3. Enable two-factor authentication methods where supported by connected platforms. While MetaMask itself does not support 2FA, exchanges and Web3 platforms you link to may offer it.

4. Store your new seed phrase offline using a hardware solution like a metal backup or encrypted USB drive. Never save it digitally on connected devices or cloud storage.

5. Monitor the old wallet address for suspicious activity. Set up blockchain alerts via services like Chainabuse or Etherscan to track any future movements.

Preventing Future Security Breaches

1. Install ad-blockers and anti-phishing extensions like MetaMask’s built-in phishing detector or third-party tools such as Trust Wallet’s Web3 Guard.

2. Avoid clicking on links in emails, social media messages, or Telegram groups claiming to be from MetaMask or crypto projects. Always navigate directly to official websites.

3. Regularly audit connected dApps and token allowances. Limit permissions to only what is necessary and remove access after completing transactions.

4. Keep your browser and MetaMask extension updated. Developers frequently patch vulnerabilities that could be exploited by attackers.

5. Use a dedicated browser profile for crypto activities. This minimizes exposure to tracking scripts and malicious ads that could lead to wallet drainers.

Frequently Asked Questions

Can I recover funds after a MetaMask wallet is drained?Recovery is unlikely because blockchain transactions are irreversible. If funds were sent to a decentralized exchange or mixer, tracing becomes nearly impossible. Reporting to blockchain analysis firms may help in rare cases involving centralized services.

Should I report the incident to MetaMask support?MetaMask cannot reverse transactions or access user wallets. However, reporting phishing attempts or suspicious domains through their official channels helps improve platform-wide security.

Is it safe to reuse the same Ethereum address after compromise?No. Once a wallet is compromised, all associated addresses should be considered insecure. Continue using a new wallet with fresh keys and avoid re-engaging with the old address.

How do wallet drainers typically gain access?Drainers often use fake airdrop sites, malicious browser extensions, or phishing pages that mimic legitimate dApps. They trick users into signing malicious transactions that approve unlimited token transfers.
