LI.FI released a hacking incident report revealing that "personal human error" during its smart contract update led to the protocol being attacked by bad actors, with an estimated 153 wallets affected and losing nearly $12 million worth of USDC, USDT and DAI stablecoins. Upon detecting the security bugs, its team immediately launched an incident response plan, successfully disabling all vulnerable aspects of the chain. The vulnerability stems from an issue that arose when validating transactions, which was related to the protocol's interaction pattern with the shared LibSwap codebase used by multiple decentralized exchanges and other DeFi protocols, due to "personal human error during the supervised deployment".
