SUI-Based Cetus Platform Discloses $223M Hack Due to Open-Source Code Vulnerability
Cetus, a trading platform operating on the sui blockchain, has revealed a critical vulnerability in open-source code that resulted in a $223 million exploit on May 22. The breach originated from an undetected flaw in third-party smart contract code, which compromised the platform’s security infrastructure.
This incident highlights systemic risks in DeFi’s dependence on external codebases. Following the exploit, Sui’s native token experienced immediate sell pressure as validators and Cetus worked to mitigate further losses. The event has prompted renewed scrutiny of open-source audits, previously regarded as a cornerstone of DeFi security.
