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

As blockchain technology rapidly gains popularity and adoption, more and more people are turning to web3 wallets as their go-to solution for storing, managing, and transacting their digital assets. However, with great benefits come great responsibilities – and when it comes to web3 wallets, one of the biggest responsibilities you have is protecting yourself from phishing scams.
Recently, the Slow Fog security team has discovered that improper use of WalletConnect on web3 wallets may pose a significant security risk of being phished. This issue exists in scenarios where the DApp Browser+WalletConnect built-in to the mobile wallet app is used. In this article, we’ll explore how to protect your web3 wallet from the dangers of WalletConnect phishing scams.

What is WalletConnect?

WalletConnect is an open-source protocol that enables secure communication between DApps and web3 wallets. It allows users to interact with decentralized applications (DApps) without compromising the security of their private keys. WalletConnect works by establishing a secure, encrypted connection between a DApp and a user’s web3 wallet via a QR code scan or deep link.

How Can Improper Use of WalletConnect Put Your Wallet at Risk?

According to Slow Fog, the vulnerability of WalletConnect lies in the way it processes and displays the DApp logo during the QR code scanning process. In the DApp logo display, there is a possibility of deliberate deception being carried out by an attacker. They may mimic the real DApp logo, leading users to believe that they are interacting with the real DApp. However, in reality, they are communicating with an illegitimate clone of the DApp created by a malicious actor.
Once the user interacts with this cloned DApp, the attackers may then prompt them to sign a transaction that sends their digital asset to the attacker’s address instead of the intended recipient’s address. As a result, users may end up losing their digital assets in such an attack.

How Can You Protect Yourself from WalletConnect Phishing Scams?

Here are some effective tips to protect yourself from potential WalletConnect phishing scams:

Tip #1: Verify the DApp Logo During the QR Code Scanning Process

Always make sure to verify the DApp logo and ensure that it’s not a fake one. This can be done by checking the DApp’s official website, social media pages, or blockchain explorer to confirm the accuracy of the logo displayed during the QR code scanning process.

Tip #2: Use the Latest Version of Your Web3 Wallet

Ensure that your web3 wallet is updated to the latest version that incorporates important security features and patches bugs that may leave you vulnerable to phishing scams.

Tip #3: Avoid Using DApp Browser+WalletConnect Built-In to Your Mobile Wallet App

While DApp Browser+WalletConnect built-in to mobile wallet apps may provide convenience, it also increases the risk of phishing scams. It’s advisable to use a standalone WalletConnect-only mobile app, preferably one that has been audited by security experts.

Tip #4: Use Anti-Phishing Tools and Services

Anti-phishing solutions can provide an additional layer of protection against WalletConnect phishing scams. These solutions can detect and block fraudulent URLs or clone websites, flagging them as potential phishing attacks.

Conclusion

Protecting your web3 wallet from phishing scams is an essential aspect of safe and secure blockchain transactions. By being cautious and vigilant, you can avoid falling prey to WalletConnect phishing scams. Remember to always verify the DApp logo during the QR code scanning process, use the latest version of your web3 wallet, avoid using DApp Browser+WalletConnect built-in to your mobile wallet app, and use anti-phishing tools and services.
