Crypto projects suffered over $194 million in losses due to malicious attacks in November, marking a 969% increase from October's $18.18 million, according to TheMarketPeriodical. The Balancer attack was the most significant, causing $134.7 million in losses by exploiting v2 forks across multiple chains. Despite undergoing 11 audits, the attack highlighted vulnerabilities in DeFi protocols. PeckShield reported that five major incidents, including exploits on Balancer, Upbit, YearnFi, HLP Bad Debt, and Gana payment, accounted for nearly $190 million of the total losses. DeFiLlama data indicates that DeFi projects alone lost $168.7 million, making November the third-largest month for exploits in the sector this year. These incidents have intensified discussions on DeFi security, with experts emphasizing the need for improved risk management and smart contract security.
