Canvas Hack Locks Out US Students During Finals Week, Forces Colleges to Postpone Exams

A hack of Instructure's Canvas learning management system has locked out students at schools and universities across the United States during finals period, forcing some colleges to postpone exams. The attack triggered a widespread outage on the platform that students depend on for exams, assignments, and course materials, creating significant disruption at institutions during one of the most critical weeks of the academic year.

Canvas, owned by Instructure, serves as the primary online platform for managing exams and coursework at educational institutions nationwide. The timing of the incident—during finals—maximized disruption, leaving students unable to access materials or complete scheduled tests. Schools and universities across the country are now recovering from the outage, according to the Associated Press, though the full scope of affected institutions and the specific nature of the hack have not been detailed.

The incident exposes the vulnerability of centralized education technology during high-stakes periods and raises urgent questions about institutional contingency planning. For students locked out during finals, the outage threatens grades, graduation timelines, and academic standing. The attack also places Instructure under scrutiny over its security posture and incident response capabilities, particularly as educational institutions have become heavily dependent on single platforms for critical academic functions. As recovery efforts continue, administrators and students alike face the challenge of rescheduling disrupted assessments and managing the academic fallout from a cyberattack that struck at the heart of the educational calendar.
