Boston's Suffolk University recently began notifying an undisclosed number of people who used their credit cards to purchase tickets to Suffolk University events that their personal information may have been accessed when ticketing vendor Vendini was hacked in March of 2013.

According to the notification letter [PDF file], customers' names, mailing addresses, e-mail addresses, phone numbers, and credit card numbers and expiration dates may have been stolen.

"Suffolk University takes this matter seriously," Danielle Manning, Suffolk University's senior vice president of finance and administration, wrote in the notification letter. "To protect you from the possibility of unauthorized charges on your credit card, we recommend that you review all charges on your account for potentially fraudulent activity."

The university is also offering all potentially affected people one year of free fraud protection services from AllClear ID.
