A recently released post-mortem report by blockchain security firm Dedaub sheds light on the catastrophic hack of decentralized exchange (DEX), Cetus, which occurred on May 22. The report exposes a critical vulnerability in Cetus’s automated market maker (AMM) logic that allowed attackers to manipulate liquidity pools and siphon hundreds of millions in crypto assets. Dedaub’s findings indicate that the exploit stemmed from a misconfigured overflow check on the most significant bits (MSB) within the protocol’s liquidity parameter handling. This oversight enabled the attackers to bypass proper input validation, injecting massive liquidity positions using only a single token unit. The manipulation caused substantial slippage and ultimately drained liquidity pools worth over $223 million. ]
