Attack Summary
The download button below is a list of affected schools by the Instructure Canvas LMS data breach. If any of the schools in the file are interested in preventing the release of their data please consult with a cyber advisory firm and contact us privately at TOX to negociate a settlement. You have till the end of the day by 7 May 2026 before everything is leaked and there will be no chance at a negociation for anyone. Instructure has not even bothered speaking to us to understand the situation or to even negociate with us to prevent the release of this data. Our demand was not even as high as you might think it is. The Company seemingly does not care about all the students affected and the institutions impacted by this data breach. They still have by 6 May 2026 to come speak with us. There is no better option but to come to an agreement with us. Not paying will only worsen the situation rather than resolving it. | Updated: 5 May 2026 | Warning: FINAL WARNING PAY OR LEAK
