A major DeFi protocol just clawed back $2.4M after hackers exploited a nasty code vulnerability. The culprit? An arithmetic overflow bug that slipped past security checks—basically, the smart contract forgot to verify its own math. Yearn's team managed to freeze the stolen funds and recover the assets before things got uglier. This incident highlights how one overlooked line of code can turn into a multimillion-dollar headache. Security audits caught it post-mortem, but the damage control worked. Another reminder that in DeFi, trust the protocol but verify the arithmetic.
