Ethereum user loses $440K in USDC after signing a malicious permit
An Ethereum user lost $440,358 in USDC after signing a malicious ERC-20 permit signature, Scam Sniffer reported on 8 December 2025. A permit is an off-chain signature that lets another address spend your tokens, so no on-chain approval appears before the theft. Anyone who signs permit requests on unfamiliar sites is at risk; check the spender and amount before signing and revoke unknown permissions.
