Whale's 1-of-1 Safe multisig drained of $27M+ after key compromise, ETH laundered via Tornado Cash
A private whale's Gnosis Safe on Ethereum, set up so a single signature could approve transactions, was taken over and drained of about $27.3M according to PeckShield; Hacken's forensics say losses may exceed $40M. Ownership passed to the attacker six minutes after the Safe was created on 4 November 2025, and the thief laundered ETH through Tornado Cash in batches while slowly unwinding a leveraged Aave position. A multisig with one signer is only as safe as that one key.
