Yearn.finance loses millions of dollars in exploit

The Ethereum-based DeFi protocol Yearn.finance (YFI) has suffered an exploit, resulting in the loss of millions of dollars worth of liquid staking tokens (LSTs), The Block reported. The attack exploited a vulnerability that allowed for the infinite minting of the yETH index token, which subsequently drained the protocol's LST pools. Following the incident, the attacker transferred 1,000 ETH to Tornado Cash.
