What was exposed
Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
Personal health data: Information about your physical or mental health: diagnoses, medications, test results, conditions, fitness and cycle tracking, therapy notes and insurance claims, held by clinics, apps, insurers and wellness services.
Social security numbers: The nine digit number the US Social Security Administration issues for work, tax and benefits, which lenders, employers, insurers and health providers use as the main key to your identity.
