ShinyHunters claimed 45 million student, teacher, and parent records from McGraw-Hill Education in April 2026, posting sample files alongside a ransom deadline. The exposed dataset includes names, contact details, and assessment-related metadata.

Education-platform data has long-tail value because student records persist for decades.
