Homie, I work in IT. I graduated from college with a degree in network security. So please consider that experience as your read my response.

This is a problem caused by companies putting in the minimum of effort to secure their systems and no effort to have a valid server back up strategy.

I'll try and keep things high level since I don't know if you're in the field or not but you sound like you aren't. In short, a driver (something low level used for an operating system to interact with a piece of hardware usually) got released which was full of bunk data. That caused a blue screen of death. This is a fixable situation you need to reboot your computer into a mode called "safe mode" and delete the bunk driver.

That's not the problem though, the problem is when you use another piece of security software called bitlocker to enceypt your enterprise equipment AND servers. You can't reboot into safe mode without a decryption key which most companies store on a piece of server software (called active directory) on a server ... which is also using both crowdstrike and bitlocker.

Your data is inaccessible and the best option is to restore from a backup which as we're seeing, few people have.

This isn't a cyber attack. This is human incompetence and business greed.
