Description

On January 12, 2023, Collegium Charter School, a non-profit educational institution based in Exton, Pennsylvania, experienced an external system breach resulting in unauthorized access to sensitive personal data. The breach was discovered the following day, January 13, 2023. The compromised information included the name of one individual in combination with their Social Security Number. This incident exclusively affected a single Maine resident, as confirmed in the breach notification submitted to the Maine Attorney General's Office by the school's legal representative, attorney Erica Lloyd of Lewis Brisbois Bisgaard & Smith LLP. The school classified the event as a hacking incident but did not disclose technical details regarding attack vectors, threat actor origins, or specific systems compromised.

Collegium Charter School initiated written notifications to the affected individual on May 24, 2023, approximately four months after breach discovery. The notification included an offer of 12 months of credit monitoring services alongside fully managed identity theft recovery assistance through an unspecified provider. No evidence suggested prior breaches affecting Maine residents within the preceding 12-month period. The delayed notification timeline between discovery (January 2023) and consumer notification (May 2023) was not explained in the submitted documentation. The school submitted a redacted copy of its general breach notification letter as part of its compliance with Maine's data breach reporting requirements.
