Meta AI Support System Flaw Enables Mass Account Takeover

Meta's AI-powered High Touch Support system contained a critical vulnerability that bypassed email verification during password resets, allowing attackers to hijack over 20,000 Instagram accounts. This incident demonstrates how AI-driven support systems can introduce new attack vectors when proper security controls aren't implemented. The ability to reset passwords without email verification represents a fundamental breakdown in authentication security that enabled mass account compromise.
