NANTUCKET, MASS. (WHDH) - Nantucket Public Schools were scheduled to close early Tuesday due to a ransomware attack, officials announced.

School district officials learned their systems were compromised by ransomware early Tuesday morning, Superintendent Beth Hallett said in a statement to 7NEWS. Hallett said all student and staff devices were shut down. Safety and security systems were also shut down, according to Hallett. 

All students in grades K-12 were scheduled to be released at 12 p.m. PreK students were released at 11 a.m. 

Hallett said students who belong to the Nantucket Boys and Girls Club were welcome to go there after dismissal. All athletic events remained scheduled as usual.

Hallett said individuals should avoid using school issued devices at home until further notice as usage “could compromise home networks.”

The Nantucket Public Schools said it will continue to communicate with families as updates become available.
