How Did Decentralized Autonomous Organizations (DAOs) Change Their Security Practices after the Attack?

Following The DAO attack, DAOs adopted significantly more rigorous security practices. This included mandatory third-party code audits, formal verification of smart contracts, and a shift towards using safer Ether transfer methods like transfer or, more commonly, the Checks-Effects-Interactions pattern.

Many DAOs also began implementing time-locks and multi-signature wallets for large fund movements to add a layer of human oversight.
