Indiana University says it has shut down a call center line it opened after discovering a computer data breach that exposed personal information about 146,000 current and former students. University spokesman Mark Land says IU hasn't received any reports that anyone's identity was stolen because of the exposure. The university announced in February that information such as names, addresses and Social Security numbers of those who attended any of IU's campuses from 2011 to 2014 was unsecured for more than 11 months because security protections weren't working correctly. Land tells The Herald-Times the school's response to the data breach cost about $130,000, including $57,000 for the call center. He says pay and benefits for IU employees who worked on the problem made up much of the remaining cost.
