If you regularly scan the news you already know that schools throughout the country -- colleges and universities, high schools, community colleges -- have been disrupted by hackers who attacked an application called Canvas. There is a lot the news stories don't explain, so let me do the reporters' job for them.
My university sent two emails about this overnight and this morning. One thing I know that you don't, if you've only read the corporate media stories, is that for about 30 minutes, students who tried to log in to Canvas were sent to a spoofed log in page that attempted to steal their passwords and other information. Presumably that happened to faculty who tried to log in as well. So that's one motive. The other is evidently that the hackers are trying to hold up the schools and/or the vendor for ransom. This is happening during final exams so it's obviously very disruptive.
Before I make my big point, let me explain that Canvas essentially replaces paper as the medium of communication between instructors and students. When I was teaching, I posted my syllabus, copies of my lecture slides, assignments, links to resources, and everything else I wanted to share with students on Canvas. I could message the class if I had anything new to tell them. Students, in turn, submitted their assignments to Canvas and the TAs marked them up and graded them on line. The grades were stored on line as well and the averages calculated automatically. In short, the slaughter of trees that normally accompanied a large lecture class was averted.
As far as I know, a few years ago, when I was teaching, the university owned the software and ran it on their own network. The information lived in the basement of a building on campus. But now, like a lot of software, it has migrated to the cloud. The university pays an annual licensing fee and the information lives who only knows where, possibly Albania. If Elon Musk gets his way (he won't), it will end up on the moon. That is why the hackers were able to attack every single user -- thousands of schools -- simultaneously. And this is a big problem for all of us, because the same kind of attack will happen again. Oh yeah -- no doubt the contract the vendor signs with the schools says that the information will all stay private, but you probably shouldn't believe it. Every student's essays, exams, grades, communication with their instructors, all of that, belongs to a huge for-profit corporation that, if it doesn't misuse the information itself, is vulnerable to hacking as we have seen.
Well, the same goes for your photoshop images, your Microsoft Office work, most of what you do with your computer or your phone. So keep that in mind.
