A security glitch at a WellPoint website may have publicly exposed the medical records and credit-card numbers of roughly 470,000 customers, including about 23,000 in Indiana. The lapse, which lasted from October through March, potentially affects a small slice of WellPoint's 2.8 million members of Anthem Blue Cross and Blue Shield in Indiana -- those who had applied for individual policies with the Indianapolis-based health insurance giant. It is the largest of three security breaches reported by WellPoint in the past 3 1/2 years. The company has attributed all three to outside vendors.
