Canvas owner reaches deal with hackers after data breach disrupts schools

Instructure, which runs Canvas, says it has reached a deal with hackers who breached its systems, stole data from almost 9,000 schools and about 275 million people, and threatened to release it unless paid; the company did not disclose whether a ransom was paid but confirmed the stolen data has been returned and that exploited free-teacher accounts have been disabled, with steps ongoing to bolster security.
