    What happened

    Vercel experienced a security breach that compromised customer accounts and internal systems, with prior compromises detected.

    The Context

    • The breach was facilitated by an infostealer infection on an employee's device, leading to unauthorized access through OAuth tokens.
    • Vercel has since implemented stricter security measures, including defaulting environment variables to 'sensitive'.
    • The incident highlights vulnerabilities in OAuth governance and the risks associated with third-party AI tools.

    Takeaway
