A whale's multisig account suffered a $27.3 million loss following a hack attributed to a private key leak, according to PeckShield. The attacker laundered $12.6 million, equivalent to 4,100 ETH, through TornadoCash and retained approximately $2 million in liquid assets. The compromised account had a leveraged long position on Aave, with $25 million in ETH used as collateral to borrow $12.3 million in DAI.
