According to BlockBeats, on July 19, TheBlock reported that LI.FI released a hacker incident report showing that "personal human errors" during its smart contract update caused the protocol to be attacked by bad actors, with an estimated 153 wallets affected and nearly $12 million worth of USDC, USDT and DAI stablecoins lost. After detecting the security vulnerability, its team immediately launched an incident response plan and successfully disabled all vulnerable aspects of the chain. The vulnerability stems from a problem that occurred when verifying transactions. The problem is related to the way the protocol interacts with the shared LibSwap code base used by multiple decentralized exchanges and other DeFi protocols, due to "personal human errors during the oversight deployment process."
