An anonymous hacked the computer systems of a provincial high school.
Hacker demanded US$5000 to return course work they held for ransom.
The encrypted data on a server contained students' work and teaching resources, principal Rachel Williams said.
The hack did not affect student and staff records but the entire school network was taken offline as a precaution.
A number of staff had lost work to the hack and work by students may have also ensnared.
