Aztec Labs probes potential $2 million exploit after 1,158 ETH moved from legacy contract

Aztec Labs is investigating a potential exploit after 1,158 ETH worth about $2 million was transferred from a legacy smart contract. The contract is tied to an Aztec payments product built in 2021 and later decommissioned four years ago. The company said the contracts are immutable and it has no administrative keys to pause the system or limit losses.
