Pierson High School

Pierson High School is a secondary educational institution located in Sag Harbor, United States of America. The school provides instructional services to adolescent students, offering a curriculum designed to support academic growth and preparation for future endeavors. As part of the local education system, it facilitates day-to-day learning activities, including classroom instruction, assessment, and student support services. The institution maintains records related to class schedules, academic performance, college admissions, payroll, and financial operations to ensure effective functioning. Its role within the community encompasses both educational delivery and the administrative management of student information.

In November 2019, Pierson High School suffered a ransomware attack that encrypted or otherwise disrupted access to its computer systems. The attack compromised a range of operational data, including class schedules, academic reports, college acceptance records, payroll information, financial balances, and student grades. Initial expectations that backups would restore service within approximately twenty‑four hours proved inaccurate, as systems remained non‑operational for a week. External cybersecurity professionals were engaged to assist with recovery efforts after internal remediation attempts fell short. Throughout the incident, the school district did not issue a public notification about the breach, leaving the community unaware of the ongoing disruption.
