Robinhood CEO: X account hacked last week due to social engineering Robinhood CEO Vlad Tenev posted that his X account was hacked last week. The attacker used social engineering tactics to trick X customer support, bypassing standard security measures like two-factor authentication and login notifications, and posted fake content about meme coins. The X security team has assisted in deleting the posts and restoring account access, and additional security protections have been added to the account.
