Insurer sending letters about security breach

BlueCross BlueShield of Tennessee will start contacting customers this week whose personal information was exposed when hard drives were stolen from the state’s largest health insurer.
The insurer has been analyzing the security breach since 57 hard drives were stolen in October from a storage closet at the Eastgate Town Center training center.
Company spokeswoman Mary Thompson said that letters are being mailed in batches starting this week as the data is being combed over and the breaches are discovered.
Chattanooga-based insurer has 3.1 million customers, but the company has not released a total estimate of how many were affected.
