CNN·medium signal

Hacking group ShinyHunters claimed responsibility for breaching Canvas LMS, stealing 3.65TB of data (~275M records) including student-teacher private messages. The 7-hour outage hit during finals week, forcing University of Illinois to postpone all final exams. Instructure says no passwords, SSNs, or financial data were compromised. Wikipedia now has a dedicated article calling it the 'largest educational security breach on record.'
