CANVAS System Is Online After a Cyberattack Disrupted Thousands of Schools reports that tens of thousands of students worldwide regained access to the online learning platform after an outage that had disrupted exams and coursework. According to Associated Press, Instructure said in an update that the system was available for most users late on Thursday. The company said the unauthorized actor exploited an issue related to Free-For-Teacher accounts and those accounts have now been temporarily shut down.
A hacking group called ShinyHunters claimed responsibility for the breach and said nearly 9,000 schools were affected with billions of private messages and other records accessed, according to a threat analyst cited in the article. Security professionals noted there is no indication that any ransom has been paid, with some critics pointing to the timing as aimed at maximizing disruption.
The article dates the report to 11 May 2026, and notes that the breach and outage spanned schools globally, including major districts in the United States.
