An online company hired by the Oskaloosa and Knoxville school districts has had a security breach that may have involved several students.  Timberline provides Medicaid billing and information for over 190 Iowa school districts.  Timberline has informed the Oskaloosa and Knoxville districts that someone got into their system, encrypted certain files and removed other information.  Timberline says the stolen files have the names of current and former students, their birthdates and Medicaid billing information. The stolen files do not include social security numbers, credit card numbers or financial information.
