A DeFi attacker drained about $72,000 from MALT by exploiting a flaw in its swap(uint256,uint256,address) function, SlowMist reported on October 3, 2026. The function recorded the caller’s input and pre-swap reserves, then called an external rebalanceHook before transferring the requested output. The hook withdrew DAI from MALT’s Capital Source, allowing the attacker to extract treasury funds and receive more MALT than the transaction should have allowed.
