A 17-year-old hacker was able to use a phishing webhook to make himself an admin in the CreatureToadz Discord server. Users who minted NFTs unknowingly sent cash to him, netting him a total of around 88 ETH (almost $350,000). However, after the hacker's real identity was uncovered shortly after the attack, the hacker returned the funds, claiming he'd intended to return it all along.
