ShinyHunters claimed 3.65 TB of data from Instructure's Canvas Learning Management System, impacting approximately 275 million students, teachers, and staff across more than 9,000 institutions worldwide. Exposed data includes private messages, emails, profile metadata, and Salesforce-integration records. The original disruption began April 30, 2026; the threat actors issued a full-dump warning on May 3.

Canvas is one of the most widely used LMS platforms in higher education and K-12. The breadth of this dataset — combined with private-message content — represents one of the largest education-sector exposures on record.
