Last week Centennial school district discovered their computer system had been infiltrated by hackers in a ransomware attack. The district cancelled all classes for a week and brought in a cybersecurity firm to help. Starting Monday, students were able to come back into the building for a few hours a week in the hybrid model, but all computer systems are still shut down. Carol Fenstermacher, Chief Communications Officer for the district, explains the impact of this attack on students and teachers.
