A major security breach has struck the Cetus Protocol on the Sui blockchain, resulting in a staggering loss of over $223 million. The attack saw attackers exploit vulnerabilities in liquidity pools, significantly depleting them and causing the CETUS token to plummet by approximately 40%. This incident highlights the growing vulnerability of decentralized finance (DeFi) systems. The Cetus Protocol temporarily halted its smart contracts as a precautionary measure to prevent further financial damage. This event has sparked debates about decentralization within the DeFi ecosystem, with some questioning the extent of control exerted by network validators in such situations.
