OKLAHOMA CITY (KFOR) — A recent data breach appears to be impacting the youngest Oklahomans and their families. Mustang, Yukon, Enid, Putnam City, and Epic Charter are just some of the districts that use PowerSchool, a computer program that stores student information. Now, that information could be in the hands of the hackers who breached the database. Mustang Public Schools said the breach happened on December 28, saying PowerSchool identified unauthorized access to its portal. The breach affected data for students and staff, including, for Mustang, records dating back to 2009.

While they are looking into the breach, district leaders say the data of staff members that could have been accessed by the hackers includes names, addresses, contact information, and social security numbers. As for students, data that could have been accessed include birth dates, grade levels, phone numbers, ethnicity, student ID numbers, and emergency contacts. Putnam City Schools says that the breach only affected schools that use PowerSchool's servers. Putnam City Schools does not. On its website, PowerSchool says it will work with districts and schools to provide more information and resources like possible credit monitoring or identify theft protection.
