Why This Breach Matters

What Brigham and Women's Hospital Held About You

Healthcare providers handle some of the most sensitive personal data — including medical records, insurance policy numbers, Social Security numbers, and treatment histories. When a healthcare company is breached, the risks go beyond identity theft to include medical identity fraud, where criminals use stolen insurance details to obtain prescriptions, procedures, or benefits in your name. Medical identity fraud is notoriously difficult to detect and correct.

Massachusetts residents are protected by M.G.L. c. 93H, which gives you the right to pursue legal remedies when a company fails to adequately protect your data.
