That's not how any of this worked. Also not how working in a large team that develops for thousands of clients works. It wasn't just one dev that fucked up here.
Crowd Strike Falcon uses a signed boot driver. They don't want to wait for MS to get around to signing a driver if there's a zero day they're trying to patch. So they have an empty driver with null pointers to the meat of a real boot driver. If you fat finger a reg key, that file only containing the 9C character, points to another null pointer in a different file and you end up getting a non bootable system as the whole driver is now empty.
If you don't understand what I just said here's some folk that spent good time and effort to explain it.
