What happened
The company says it secured its network, reviewed the files and notified law enforcement. The sample letter does not give the initial access method, a national victim count or the data fields for an individual. Vermont’s register lists Social Security numbers, government ID numbers, financial account codes, payment account information and health records. The Vermont count applies to that state. The fields in an individual letter determine which precautions apply.
