The hacker who claimed responsibility for the $200 million Euler Finance decentralized finance (DeFi) protocol exploit has returned some of the stolen funds. He hacked the product in early March 2023 and spent several weeks negotiating with developers who asked him to transfer back a large amount of stolen funds. He ended up transferring 51,000 Ethereum (ETH) worth $89.59 million.
Such data was provided by the researchers of the analytical company LookonChain, who attached a link to the transaction in the blockchain explorer. They confirmed that almost $90 million was sent back to the smart contract of the Euler Finance protocol.
However, the researchers emphasized that the attacker also made several other transactions. He transferred several tens of millions of US dollars (USD) in Dai (DAI) stablecoin to unknown wallets. The researchers recalled that last week the developers of Euler Finance offered a reward of $1 million to anyone who provides information about the hacker. They asked him to return the stolen cryptocurrencies in exchange for a promise not to sue the cybercriminal.
The Euler Finance lending protocol was exploited a few weeks ago. As a result, the attacker made 4 transactions in Dai (DAI), Wrapped Bitcoin (wBTC), Staking Ether (sETH), and USDC stablecoin.
The cybercriminal used a standard scheme. He activated the flash credit to carry out the attack, fooling the protocol and its participants. Native EUL tokens have risen in value by almost 25% over the past 24 hours, with the biggest price movement coming after a hacker put the tokens back into the protocol. This action likely provoked positive sentiment among traders. Earlier it became known that one of the users asked the hackers to return 75 ETH, and received a transfer of 100 ETH from the attacker.
