Baker is a private university based out of Kansas with about 2,300 students and faculty. The information stolen varies from person to person, but includes name, date of birth, Driver's license number, financial account information, health insurance information, medical information, passport information, Social Security number, student identification number, and tax identification number.

The company claims they have about 50 million customers, so this would be nearly half of them.
