A warning has been issued to Butler University saying more than 160,000 students, faculty, staff and alumni may have had their personal information accessed by hackers. The Indianapolis school learned about the data breach when California officials contacted them last month to say they'd arrested an identity theft suspect who had a flash drive with Butler employees' personal information on it. The suspect has no affiliation with the school. On that flash drive: birthdates, social security numbers and bank account information. School officials are offering those affected a year of free credit monitoring and urged them to keep an eye on their bank accounts and credit scores.
