  Yes, there have been several instances where blockchain vulnerabilities have been exploited to carry out cryptocurrency hacks. One notable example is the DAO hack in 2016, where an attacker exploited a vulnerability in the smart contract code of the Decentralized Autonomous Organization (DAO) and stole approximately $50 million worth of Ether. This incident led to a hard fork in the Ethereum blockchain to recover the stolen funds.
