WellPoint Inc. has notified 470,000 individual insurance customers that medical records, credit card numbers and other sensitive information may have been exposed in the latest security breach of the health insurer's records.
The Indianapolis company said the problem stemmed from an online program that customers can use to track the progress of their application for coverage.Spokeswoman Cynthia Sanders said an outside vendor had upgraded the insurer's application tracker in October and told the insurer all security measures were back in place.
But a California customer discovered that she could call up confidential information of other customers by manipulating Web addresses used in the program. Customers use a website and password to track their applications.
