Michigan State University has told more than 27,000 students that their Social Security numbers could have been compromised by a hacker who broke into a computer server.
The school on Tuesday informed students of a security breach on the College of Education's server, The State News reported.
The server held information such as students' names, addresses, courses and personal identification numbers. When the breach was discovered in April, the server was taken offline and an investigation began.
The college no longer maintains student Social Security numbers on its server.
Last week, a breach was found within the university's human resources department, possibly allowing a hacker to gain access to the Social Security numbers of all university employees and retirees.
Earlier this year, Michigan State warned more than 40,000 patrons of its Wharton Center performing arts venue that a hacker had broken into a computer server involved in credit card processing. There was no definitive evidence that credit card data was stolen or copied.
