PANews reported on May 27 that according to The Block, Cetus, a decentralized trading platform based on Sui, confirmed that there was a vulnerability in the open source library used in its CLMM smart contract, which caused hackers to manipulate the pool price and repeatedly withdraw liquidity through flash swaps, eventually stealing about $223 million. The vulnerability originated from an integer overflow check error in the inter_mate library. Cetus has disabled the core contract and frozen some of the attacker's address funds, but about $60 million has still been transferred to Ethereum. The platform is now preparing an upgrade and rollback proposal, and is offering a $5 million reward for clues to solve the case.
