Chaos erupted at schools and colleges across the United States on Thursday when a cyberattack targeted the Canvas online learning platform, disrupting final exams for many students. The parent company, Instructure, announced that it took Canvas offline after detecting unauthorized activity. By Friday morning, the platform was restored. The cyberattack was linked to the same group responsible for a previous data breach disclosed by Instructure just a week earlier. The ransomware group, known as ShinyHunters, claimed to have accessed data from 275 million individuals connected to 8,800 schools. This data included usernames, email addresses, student ID numbers, and messages exchanged on the platform, although Instructure stated that sensitive information such as passwords and financial details were not compromised. The attack caused significant disruption, leading institutions like the University of Illinois to postpone exams and others to adjust deadlines. This incident highlights a growing trend of cyberattacks on educational platforms, following a similar breach last year involving PowerSchool, which affected millions of students worldwide.
