Incident Overview
They abused an immutable escape-hatch function that lacked proper ownership checks, using manipulated or fake rollup proofs to withdraw assets without corresponding deposits. Approximately $2.16 million (1,158 ETH, 150,000 DAI, and 0.47 renBTC) was drained. Aztec Labs confirmed the affected contract is unrelated to the current Aztec Network or the AZTEC ERC-20 token and that they have no control over the immutable old contracts.
