About 230,000 Anthem Blue Cross customers have been warned that their personal records may have been accessed during a faulty upgrade of the company's website.
Anthem spokeswoman Cynthia Sanders says site users were able to manipulate Web addresses to access confidential information for a short period following an upgrade, when security measures were not reinstated properly.
Sanders alleges the site was primarily misused by attorneys seeking information for a class-action lawsuit.
Anthem sent letters to customers who may have been affected and offered a free year of identity protection services. In the letter, the company also says the attorneys have relinquished all ill-gotten information.
