Zabu Finance, a yield farm decentralized protocol built on top of the Avax blockchain, faced the big first hack related to the Avalanche chain last week. An attacker took advantage of a vulnerability and withdrew $3.2 million worth of several cryptocurrencies. The attack had its root in a pool of a token called Spore, which allowed the attacker to mint over 4.5 billion of the native token of the protocol (Zabu).
