An experimental investment fund based on the digital currency ether has been hacked, with about $55 million worth of the currency stolen. Founders of the $150 million fund, known as the Decentralized Autonomous Organization, shut it down in the wake of the June 17 hack. The attackers appeared to have exploited a loophole that essentially allowed a DAO stakeholder to create an identical fund and move money into it. The DAO’s founders are planning to “fork” the code and effectively void the hacker’s transactions.”]
