Here’s a fun story from Sophos of a Pennsylvania mom who hacked school district computers in order to improve her children’s grades. She did this while working as an employee of the school district, so this in not quite the feat you might think it is. Nevertheless, she was able to access a lot of other secure personal and payroll records for the district, using the Superintendents user ID and password. Point being that you never know who you know who might have unauthorized access to your information.
She was revealed when some teachers questioned why the Super was inspecting their grading records. The Superintendent had not ever looked at the grades, and the District IT department froze the record system. Mom was revealed as the perpetrator, and faces both fines and jail time.
