The University of Florida in Gainesville has disclosed that a breach discovered in January exposed personal data on 97,200 students, faculty and staffers who attended or worked at the school between 1996 and 2009. The latest breach involved servers that hosted free email services and online course offerings for faculty members, as well as websites for fraternities and sororities. Hackers accessed names and Social Security numbers. The University is notifying those affected by the breach, but does not have current contact information for about 5,000 potential victims. Meanwhile, the school said in November that the names, birth dates, Social Security numbers and addresses of more than 330,000 current and former College of Dentistry patients had been exposed in a computer intrusion discovered on October 3, 2008. An undated statement now on its website says a configuration error in the school’s online directory service opened a path for hackers to access personal information for about 100 people.
