Instructure Canvas hack update: ShinyHunters claim second hack, deface school websites

ShinyHunters reportedly breached Instructure again and defaced several Canvas school login pages.

The group issued a deadline-based extortion threat, saying it would leak stolen data unless Instructure negotiates.

Instructure had said the attackers exploited an issue tied to Free-For-Teacher accounts.

The incident points to an ongoing intrusion at a major education platform, with potential risk to schools, students, and staff.
