Instructure Confirms Canvas Data Breach as ShinyHunters Post List of 8,800 Schools

The reach of Canvas across thousands of schools raises privacy and notification stakes worldwide.

Overview

  • ShinyHunters has posted a list of 8,809 institutions it says were affected and claims 280 million records, while also alleging a breach of Instructure’s Salesforce system.
  • Instructure says the breach exposed names, email addresses, student ID numbers, and private messages, with no evidence of passwords, dates of birth, government IDs, or financial data.
  • The company reports it contained the attack, revoked credentials and access tokens, rotated application keys, deployed patches, and increased monitoring.
  • TechCrunch reviewed a sample that included data from two U.S. schools but could not verify the full list or the hackers’ scale claims.
  • Instructure says services are back and the probe with outside experts and law enforcement continues, which may lead to notices to schools and users.
