A multi-signature wallet was hacked, with over $27.3 million in assets at risk. According to on-chain security monitoring, the hacker successfully gained control of the wallet. The recent operation was particularly aggressive — withdrawing 1,000 ETH from Aave, equivalent to approximately $3.24 million. Even more alarming, the hacker subsequently transferred a large amount of assets to TornadoCash for mixing and laundering. As of now, 6,300 tokens have been sent to the mixer. This incident once again sounds the alarm: even "standard security configurations" like multi-signature wallets are vulnerable to being compromised. While the DeFi ecosystem offers abundant liquidity, user asset security requires multiple layers of protection — from wallet architecture and private key management to interaction risks, every link must be taken seriously.
