A cyber-attacker outsmarts a “smart contract”

From The Economist

“IS IT theft if no rules are broken? That is what users of the DAO, a futuristic investment fund, were left pondering after June 17th, when an unknown attacker made off with around 3.6m “ether”, an online currency similar to bitcoin. As cyber-heists go, it was a big one: the ether were worth about $55m at the time of the attack, about a third of the DAO’s assets. But the DAO, which stands for Decentralised Autonomous Organisation, does not have rules as such, or staff to enforce them: instead, it has computer code, which is supposed to embody its purpose and to operate automatically.
