Details of the hack. The hacker exploited a vulnerability in the reward distribution protocol, allowing him to issue additional tokens. The attacker then sold them, collapsing the price of the native token of Zeed (YEED) to zero, and earned more than $1 million.

Analytics firm PeckShield noted that the stolen cryptocurrency was transferred to an “attack contract,” a smart contract that automatically executes an exploit. However, the hacker did not withdraw the funds from the address before setting it to self-destruct, and the coins were permanently stuck in the contract. On April 21, at 7:15 UTC the contract was destroyed.
