University of Florida officials say an unauthorized intruder accessed a College of Dentistry computer server containing personal information of more than 344,000 current and former dental patients.
The information included names, addresses, birth dates, Social Security numbers and dental procedure information for patients dating back to 1990.
According to a university news release, the breach was discovered Oct. 3, when college staff members were upgrading the server and found software had been remotely installed on it.
While UF officials have no evidence the intruder used the information for fraudulent purposes, letters were mailed to people who had information on the system to alert them.
