Instructure Canvas breach exposes students' messages at nearly 9,000 schools
Edtech firm Instructure confirmed attackers exploited a platform flaw in its Canvas LMS and took names, emails, student IDs and messages between users; ShinyHunters claimed data on about 275 million people at nearly 9,000 schools and later defaced login pages in a second breach. Instructure said it reached an agreement with the group to delete the data, and a House committee sought testimony.
