WOLCOTT, Conn. (AP) - A Connecticut school district's teachers are working without computer access less than a week after a second malware attack targeted the district's servers.

The Republican American reports the district shut any computers connected to the Wolcott school district networks Sept. 4 after a staff member reported suspicious activity on a district computer.

The district was the victim of a three-month ransomware attack this summer that blocked all five Wolcott schools from accessing internal files, as well as staff in the central office and business office.

Superintendent Anthony Gasper says the district might turn on a few computers for school secretaries to use Tuesday, but the remaining computers will remain shut down.

The district has hired cyber security firm Kivu to help them recover from the attacks.
