Odaily Planet Daily News According to the annual "Web3 Security Report" by blockchain security company Hacken, due to protocol improvements, enhanced bridging, and more advanced encryption measures, losses in the DeFi sector caused by security incidents decreased by 40% from 2023 to 2024. Meanwhile, as CEX became a primary target for access control vulnerabilities and other significant security risks, CeFi security incidents more than doubled, with losses rising to $694 million. The surge in attack incidents is mainly attributed to access control vulnerabilities and notable events, such as the DMM exchange hack in Q2 and the WazirX hack in Q3. These incidents involved private key leaks and multi-signature exploitations, resulting in thefts of $305 million and $230 million from the two exchanges, respectively. The report indicates that financial losses in DeFi significantly declined in 2024, dropping from $787 million in 2023 to $474 million this year. Among these, losses related to bridging-related security incidents sharply decreased from $338 million in 2023 to $114 million in 2024. Despite improvements in DeFi, such as multiparty computation and zero-knowledge proofs, challenges remain; in fact, access control vulnerabilities account for nearly half of all DeFi losses, such as the $55 million Radiant Capital hack.
