Devastating Vyper Copycat Attack Hits BNB Smart Chain, $73K Exploited! BNB

Devastating Vyper Copycat Attack Hits BNB Smart Chain, $73K Exploited! BNB Smart Chain is a decentralized platform that has recently suffered from copycat attacks due to a vulnerability in the Vyper programming language. This issue is similar to the exploit that occurred on the decentralized finance protocol Curve Finance. As a result of these attacks, around $73,000 worth of cryptocurrencies on BSC has been stolen across three different exploits. This is concerning, especially because similar exploits targeting liquidity pools on Curve Finance have resulted in losses exceeding $41 million. The vulnerability was caused by a malfunctioning reentrancy lock on Vyper versions 0.2.15, 0.2.16, and 0.3.0. This programming language is widely used for Web3 projects and was designed for the Ethereum Virtual Machine. The Vyper vulnerability could also affect other protocols that use the afflicted Vyper versions. In response to the exploit, a number of white hat and black hat hackers have been battling it out on-chain trying to disrupt each other’s exploit attempts or efforts to recover funds. One potential whitehat, known as “c0ffebabe.eth,” even managed to grab some funds to store for safekeeping. On July 30th, they sent an on-chain message asking affected protocols to contact them to organize the return of the stolen funds. Source
