The DAO Hack The reentrancy problem probably ranks highest among blockchain security vulnerabilities programmers coded into smart contracts. Reentrancy drains an account through multiple expenditures for the same transaction.

A Multi-Stage Attack. This exploit in the DAO is clearly not trivial; the exact programming pattern that made the DAO vulnerable was not only known, but fixed by the DAO creators themselves in an earlier intended update to the framework's code.Ironically, as they were writing their blog posts and claiming victory, the hacker was preparing and deploying an exploit that targeted the same

But the Etherum Foundation, which manages the Ether mock-dao-hack. I wanted to recreate a recurisive send exploit similar to the one used by an attacker to drain "The DAO".

An attack has been found and exploited in the DAO, and the attacker is currently in the process of draining the ether contained in the DAO into a child DAO.The attack is a recursive calling vulnerability, where an attacker called the “split” function, and then calls the split function recursively inside of the split, thereby collecting ether many times over in a single transaction.

In response, DAO participants voted for a “fork”, which would release a new version of the Ethereum software, which would wipe The DAO from Ethereum's Blockchain, effectively erasing the withdrawal of funds that the exploit executor earned from their hack of the DAO.
