Hacker breached data at Harvard University

Harvard University is notifying thousands of graduate students and applicants that their personal information may have been exposed by a data breach.

The Ivy League school says a computer hacker gained entry to its server last month.

Harvard says about 10,000 of last year's applicants may have had their personal information compromised, with 6,600 having their Social Security numbers exposed.

The school says it will provide the applicants with free identity theft recovery services and help them with credit monitoring and fraud alerts.
