Robinhood founder Vlad Tenev's mnemonic phrase was leaked during a livestream, leading to a significant security breach. A hacker gained control of Tenev's address and manipulated it to purchase a $1 meme coin, prompting a frenzy that saw the token's market cap soar from $500,000 to $14 million before crashing. The trading volume reached approximately $20 million within two hours. Following the freeze of the compromised address, the hacker shifted operations to the BNB Chain. There, they issued new tokens and engaged in trading activities, ultimately cashing out. This incident highlights the vulnerabilities associated with mnemonic phrase exposure and the rapid impact of social media-driven trading.
