Canvas data breach hits 44 Dutch schools in May 2026, exposing student emails, IDs, and messages in global cyberattack.
A major cyberattack on the widely used Canvas education platform has exposed student and staff data from dozens of institutions, including 44 schools and universities in the Netherlands.
The breach, revealed on May 5, 2026, is linked to the hacking group ShinyHunters, which claims to have accessed a database belonging to Instructure, the U.S.-based company behind the platform.
According to reports, the stolen data includes names, email addresses, student identification numbers, and messages exchanged between users on the platform.
The attack is part of a much larger global breach that may have impacted up to 275 million individuals across nearly 9,000 educational institutions worldwide.
Among the affected institutions are major universities and colleges, including the University of Amsterdam and the Vrije Universiteit Amsterdam, along with several applied sciences institutions and secondary schools.
Security experts say the attackers gained unauthorized access to backend systems used by Canvas, allowing them to extract large volumes of user data. However, initial findings indicate that highly sensitive information such as passwords, financial data, and government identification details were not compromised.
The incident has raised concerns about the security of widely used education platforms, which store large amounts of personal and academic data. Institutions affected by the breach are continuing to assess the impact and have begun notifying students and staff while working with cybersecurity teams to contain risks.
The investigation is ongoing as authorities and the platform provider work to determine the full scale of the breach and whether the stolen data will be publicly released.
