Hackers deface school login pages after claiming another Instructure hack

ShinyHunters allegedly defaced Canvas login pages at multiple schools using Instructure’s platform.

The pages showed an extortion message and a threat to leak stolen data unless Instructure negotiates.

The incident follows an earlier breach that exposed student information, suggesting escalating pressure on the company.

Schools using Canvas may face renewed security and privacy risks as attackers target education-sector portals.
