How much personal info will be leaked by the recent Canvas hack?? [ reddit.com/r/cybersecurity ]

The flava:

So apparently Canvas got hacked by ShinyHunters (3?!) times and is currently completely down. The cybercriminal group said the deadline is on May 12st, and if Instructure doesn't comply, they'll leak the PII of all students and teachers. I'm not a cybersecurity major, and I don't know much about Canvas, but how much will we be affected if no deal is reached? Like, how much information is typically stored on Canvas, and will they be able to figure out more through what is available in the system? I'm genuinely concerned....
