$BTC The Cetus hack is a major security incident that occurred on May 22,2025.Attackers exploited a smart contract vulnerability by carefully constructing parameters to trigger an overflow while bypassing detection,and ultimately exchanged a minuscule amount of tokens for a huge amount of liquidity assets.This incident has exposed the weaknesses of DeFi protocols in verifying the boundary conditions of mathematical functions and highlighted the potential risks of cross-chain protocols.Although some of the stolen funds have been frozen,the event has severely impacted the SUI ecosystem and investor confidence.It once again reminds project teams to strengthen code audits and establish emergency response mechanisms.
