[DEX Atomic Attacked Due to Signature Replay Vulnerability, Losses Around 30,000 USDC] According to SlowMist monitoring, the decentralized exchange Atomic Protocol was attacked due to a signature replay vulnerability, resulting in a loss of approximately 29,984 USDC. The vulnerability originated from contract 0xa806010f, which lacked binding of position ID, position manager, caller, nonce, deadline, and chain ID in the signature digest. This allowed the same manager signature to be replayed across 21 different position IDs, enabling unauthorized full LP destruction under flash loan price manipulation, without TWAP or slippage checks.
