Big Rapids, Mich. Ferris State University says a data security breach put identifying information of thousands of people at risk of being accessed.
The Big Rapids school says it learned July 23 that an unauthorized person evaded network security and gained access to a computer that's used to operate its website. About 39,000 people's names and Social Security numbers were in files that were accessible.
The school says it shut down the server and hired a computer forensic firm to help it investigate and block further unauthorized access. The investigation didn't find any evidence that the unauthorized person viewed or removed any information.
Affected people are being notified by letter.
The school also mailed letters to 19,000 current, former and prospective students whose names and student identification numbers were accessible.
