The TVL of DeFi has surpassed $100 billion for the first time since 2022, with several notable security incidents occurring up to this point, such as Mixin Network (with losses of approximately $200 million), Euler Finance (with losses of approximately $200 million), and KyberSwap (with losses of approximately $48 million), among others. The losses from these DeFi security incidents are significant.

This topic will cover well-known DeFi security incidents and common attack vectors in DeFi, including manipulation of price oracles, reward manipulations, private key leaks, inadequate permission controls, and logical errors, among others. This session aims to enhance the understanding of blockchain security issues among Web 3 developers and security professionals through sharing problems frequently encountered in blockchain security audits and case analyses of security incidents. By doing so, it hopes to promote the construction of safer blockchain projects.
