TrustWallet Browser Extension Vulnerability and How to Protect Your Wallet

On April 22nd, the founder of Slow Fog, Yu Xian, quoted Trust Wallet’s announcement on social media stating that if users use the Trust Wallet browser extension and create a wallet between November 14-23, 2022, the wallet will be at risk. The fundamental reason is that the MT19937 pseudo-random number generator used by the TrustWallet browser extension at that time did not provide sufficient randomness, resulting in the private key being cracked.
Founder of Slow Fog: There are risks in using TrustWallet browser extensions to create wallets from November 14-23 last year
In November 2022, TrustWallet users who created a wallet using the TrustWallet browser extension between November 14-23, 2022 may have put their wallets at risk due to a vulnerability discovered by Slow Fog’s founder, Yu Xian. The vulnerability stems from the use of the MT19937 pseudo-random number generator, which did not provide enough randomness, leading to the cracking of private keys. In this article, we will explore the details of this vulnerability and provide guidance on how to protect your wallet.
What is the TrustWallet Browser Extension?
TrustWallet, a subsidiary of Binance, is a decentralized wallet that allows its users to store, manage and exchange their cryptocurrencies, including Bitcoin, Ethereum, and Litecoin. The TrustWallet browser extension allows users to access their wallet easily through their web browser, providing a more convenient way to manage their digital assets.
The Vulnerability and its Impact
The MT19937 algorithm used by the browser extension provides random numbers for the creation of private keys. However, it was discovered that the algorithm was not generating enough entropy, creating a predictable pattern in the generated keys. This, in turn, made it easier for hackers to crack the private keys and access the funds stored in the wallets.
The vulnerability only affects users who created a wallet using the TrustWallet browser extension between November 14-23, 2022. If you fall under this category, ensure you take the necessary steps to protect your wallet.
How to Protect Your Wallet
If you created a wallet using the TrustWallet browser extension within the affected period, below are some steps you can take to protect your wallet:
Generate a New Wallet
The first and most important step to take is to generate a new wallet. This will create a new private key, making it impossible for hackers to access your funds stored in the compromised wallet.
Transfer Funds to the New Wallet
After generating a new wallet, ensure you transfer all your funds from the compromised wallet to the new one. This step will ensure that you don’t lose your funds in case of any attack on the compromised wallet.
Destroy the Compromised Wallet
The next step is to destroy the compromised wallet. This will ensure that there’s no link between the compromised wallet and the new wallet. Once the compromised wallet is destroyed, you can fully rely on the new wallet for all your cryptocurrency needs.
In Conclusion
The TrustWallet browser extension vulnerability discovered by Slow Fog’s founder, Yu Xian, is a serious issue that affects TrustWallet users who created a wallet between November 14-23, 2022. It is recommended that you take the necessary steps to secure your wallet by generating a new wallet, transferring your funds, and destroying the compromised wallet. Always remember to stay vigilant and cautious when dealing with cryptocurrencies to protect your digital assets.
FAQs
#Q1. What is a private key and why is it important?
A private key is a secret code that clients use to sign transactions on the blockchain network. It is the password to your wallet and serves as the authority to access your digital assets. Losing your private key is equivalent to losing your physical wallet.
#Q2. Can the TrustWallet browser extension vulnerability affect other TrustWallet users who did not create a wallet within the affected period?
No, only users who created a wallet using the TrustWallet browser extension between November 14-23, 2022, are affected by the vulnerability.
#Q3. Are there any other TrustWallet features that might also be vulnerable?
Currently, there are no reports of other TrustWallet features being vulnerable. The vulnerability only affects the TrustWallet browser extension within the specified period.
