More than 197,000 personal records were exposed in a security breach at the McCombs School of Business at the University of Texas, school officials said this week.

Initially discovered late last Friday, the breach occurred as early as April 11 and has exposed Social Security numbers and other information of alumni, faculty, staff and current and prospective students of the business school. IT staff at the university are investigating the source of the breach.

In the meantime, the university has set up a website and toll-free numbers to direct those potentially affected to protect their identities. Officials will also send notification to all those on the affected database, whether their Social Security numbers were accessed or not.
