Multiple universities forced to reschedule final exams after Canvas cyber incident

Instructure's Canvas platform was targeted by the ShinyHunters cybercriminal group, which exploited Free‑For‑Teacher accounts to deface pages, prompt a ransom demand, and previously exfiltrate an estimated 3.6 TB of data from over 9,000 schools; the outage disrupted universities and K–12 districts, forced temporary account takedowns, and triggered investigations involving law enforcement and external cyber experts.
