Canvas System Is Online After a Cyberattack Disrupted Thousands of Schools

Canvas, a widely-used online learning platform serving tens of thousands of schools globally, was knocked offline by a cyberattack just as students were preparing for final exams. A hacking group called ShinyHunters claimed responsibility, saying they accessed nearly 9,000 schools' data including billions of private messages, and demanded individual schools negotiate settlements directly. The platform operator Instructure has since restored service to most users after discovering the hackers exploited a vulnerability in free teacher accounts, though the company hasn't disclosed whether any ransom was paid or the full extent of data compromised.
