Reentrancy is probably the most famous Ethereum vulnerability, and it surprised everyone when discovered for the first time. It was first unveiled during a multimillion dollar heist which led to a hard fork of Ethereum. Reentrancy occurs when external contract calls are allowed to make new calls to the calling contract before the initial execution is complete. This means that the contract state may change in the middle of its execution, as a result of a call to an untrusted contract or the use of a low level function with an external address. One of the major dangers of calling external contracts is that they can take over the control flow. In a reentrancy attack, a malicious contract calls back into the calling contract before the first invocation of the function is finished. This may cause the different invocations of the function to interact in undesirable ways.
