Aetna was notified by one of its vendors, Concentra Preferred Systems, that one of its offices, along with five other business tenants in the same building, was broken into by burglars in late October. Random items were stolen from each tenant in the building, ranging from cash, pharmaceuticals and movie passes to DVDs and other easily transportable property. Among the missing items was a lock-box containing back-up and blank data tape cassettes. Some of the tapes contained data from numerous Concentra health plan clients, including Aetna.
Below is additional information from Concentra and Aetna about the incident.
