Baltimore cancelled school completely, recently.(1,2) It seems some hacker gained access to the school network and password protected it so that the network was inaccessible to students, staff, teachers and techies. It’s one of the new cutting edge crazes in the world of black hat hacking (as opposed to white hat hacking, look ’em up). The techie contacts the school, in some manner, and offers to un-password protect the network for $$$$$. The article reported that the shutdown was not related to the Great Coronavirus Epidemic of 2020. I have another opinion seeing that the crime has just been reported to law enforcement. In other words, they don’t know.
In my mind, having had some experience with virtual learning, I can see Beavis and Butthead 
sitting on the sofa laughing their collective asses off because now they don’t have to turn in the virtual algebra assignment that was required during their COVID-19 quarantine due that day that they haven’t done, yet.
More Unintended Consequences but apparently this is not the first rodeo for BCPS district.(3)
