The recent attack that drained $197 million from Euler Finance was dubbed the biggest decentralized finance (DeFi) hack of 2023 so far. However, this may not hold for much longer as the hacker reportedly had a change of heart. On March 18, roughly 3,000 Ether (ETH) ($5.4 million) were returned to Euler Finance’s deployer address from the Euler Finance hacker’s address. Blockchain investigator PeckShield identified three transactions that were used to send the funds. Euler Labs (@eulerfinance) March 15, 2023 The exploiter was able to drain $197 million through multiple transactions and later used a multichain bridge to transfer the funds from the BNB Chain to Ethereum. Euler Finance demanded that the hacker return 90% of the funds within 24 hours to avoid possible jail time. Source: Cointelegraph
