Delbarton School

The Maine Office of the Attorney General disclosed a data breach affecting Delbarton School, which transpired between May 14–20, 2020 and was reported on December 11, 2020. The incident stemmed from an external system breach (hacking), compromising the personal data of 26,084 individuals, including 71 Maine residents. The exposed information included Social Security numbers (SSNs), a highly sensitive dataset that significantly elevates risks of identity theft and financial fraud. In response, the school is providing 24 months of identity theft protection services to affected parties. The breach’s scale—spanning tens of thousands of records—and the nature of the leaked data (SSNs) underscore severe reputational damage and long-term operational consequences for the institution, particularly given its responsibility for safeguarding student, faculty, and staff information.
