Reveal $8.7M Uniswap Wallet Hack Through EIP-712 Vulnerability

A 61-year-old wallet lost $8.7M due to an EIP-712 vulnerability. Harry Denley revealed the exploit involved unsafe delegate calls allowing attackers to disable ERC-721 and ERC-1155 tokens. The wallet used OpenZeppelin Defender, which was compromised through the EIP-712 signing process. This incident demonstrates risks in automated contract management with delegated calls and off-chain message signing.
