IOWA CITY, Iowa (AP) -

An Iowa community college says that hackers may have stolen personal information for thousands of students who applied to take credit classes in the last eight years.

Kirkwood Community College in Cedar Rapids said Monday that "sophisticated hackers" using an international IP address hacked into its website on March 13.

The school says the hackers gained access to archived application information from February 2005 to present that included names, social security numbers, birthdates and other information. No financial information was stored in the system.

The school says it has contacted those who may have been affected to offer free assistance, including guidance from identity theft and restoration experts and credit monitoring alerts.

Kirkwood says more than 25,000 students took courses last year. It has locations in 7 eastern Iowa counties.
