Euler Finance hacker starts returning stolen Ether

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 Financeโ€™s deployer address from the Euler Finance hackerโ€™s address. Blockchain investigator PeckShield identified three transactions that were used to send the funds.

Cointelegraph confirmed that the hacker transferred 1,000 ETH per transaction to Eulerโ€™s deployer account. However, chances that the hacker will return the entire loot of $197 million remain slim, as no more outbound transactions were recorded at the time of writing.

On March 16, Euler Finance announced a $1 million reward to track down the hacker and retrieve the funds.

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.

Soon after a $1 million bounty was announced, the stolen funds were moved into the crypto mixer Tornado Cash.

Euler Finance demanded that the hacker return 90% of the funds within 24 hours to avoid possible jail time.
