According to reports, the Slow Fog security team has discovered that improper use of WalletConnect on Web3 wallets may pose a security risk of being phished. This issue exists in scenarios where the DApp Browser+WalletConnect built-in to the mobile wallet app is used.

Slow Fog: Alert to the Risks of WalletConnect Phishing in Web3 Wallets

With the rise of decentralized applications (DApps) and blockchain technology, more and more people are using Web3 wallets to store and manage their digital assets. However, recent reports have revealed that there is a security risk associated with the improper use of WalletConnect on Web3 wallets. In this article, we will explore the potential threats of phishing attacks via WalletConnect and provide practical tips on how to protect your Web3 wallet from such attacks.

Understanding the Security Risk of Using WalletConnect on Web3 Wallets

According to the Slow Fog security team, there is a vulnerability in scenarios where the DApp Browser+WalletConnect built-in to the mobile wallet app is used. Basically, when the user opens a DApp on their mobile device, the DApp will prompt the user to connect with their Web3 wallet via WalletConnect. If the user confirms the connection, the DApp will be able to access the user’s account and perform operations on their behalf.
However, the problem is that phishing attackers can create fake DApps that look similar to legitimate ones. When users unknowingly connect their Web3 wallets to these fake DApps via WalletConnect, the attackers can steal their private keys and take control of their funds. This is because WalletConnect does not provide users with a way to verify that the DApp they are connecting to is legitimate.

Tips to Prevent Phishing Attacks via WalletConnect

To protect your Web3 wallet from phishing attacks via WalletConnect, you can follow these tips:

1. Only Use DApps from Reputable Sources

To avoid connecting to fake DApps, you should only use DApps from reputable sources that have a good track record. For example, you can use DApps that are listed on popular blockchain explorer websites or recommended by trustworthy communities such as r/ethereum or r/binance.

2. Check the DApp’s URL and SSL Certificate

Before connecting your Web3 wallet via WalletConnect, you should check the DApp’s URL to make sure it is a legitimate one. You can also check the SSL certificate of the website to ensure that it is secure and valid. In addition, you can use browser extensions such as MetaMask or MyEtherWallet to detect phishing websites.

3. Don’t Share Your Private Key or Seed Phrase

Never share your private key or seed phrase with anyone, even if they claim to be from a legitimate company. Keep your private key and seed phrase stored in a secure place, such as a hardware wallet or a password manager. If you suspect that your private key or seed phrase has been compromised, you should transfer your funds to a new address immediately.

4. Use Two-Factor Authentication (2FA)

Two-factor authentication (2FA) can add an extra layer of security to your Web3 wallet. You can enable 2FA by using an authenticator app such as Google Authenticator or by receiving SMS codes to your phone. By doing so, you will need to provide an additional code to access your Web3 wallet, even if your private key is compromised.

Conclusion

In conclusion, the security risk posed by improper use of WalletConnect on Web3 wallets is a serious concern for crypto holders. However, by following the tips outlined in this article, you can reduce the likelihood of becoming a victim of phishing attacks via WalletConnect. Remember to only use DApps from reputable sources, check the DApp’s URL and SSL certificate, never share your private key or seed phrase, and enable two-factor authentication (2FA) for your Web3 wallet.
