The Social Security numbers of 75,000 people were exposed in a data breach at the University of Wisconsin-Milwaukee.
The school said Wednesday that a malicious program was found May 25 on a system that had the personal data of its students, faculty and staff, the Journal Sentinel reported Thursday.
Though the data could be misused to open fraudulent bank accounts, "we don't believe the motive was identity theft," Tom Luljak, the school's vice chancellor for university relations, told the paper. "We are a research institution with a significant number of projects under way. It is theorized that this may have been an attempt to look at work being done."
The university has mailed letters to the affected individuals informing them of the exposure.
