The protocol had previously tried to negotiate with the exploiter, requesting that they return 90% of the funds they stole within 24 hours, otherwise it would face legal action. No response was received, and 24 hours later, Euler offered a $1 reward for any information leading to the capture of the exploiter.

The hacker has made other transactions, including a transfer of 1,000 nETH, roughly $1.65 million at the time, via sanctioned Tornado Cash crypto mixer.

According to blockchain analytics firm PeckShield, around 100 ETH were sent to a wallet address likely owned by one of the victims. A chain message sent by the wallet address had asked the attacker to return his "life savings."
