I should add that I don't know if the channel definition update files were privately signed or not; what I meant is that I presume they do not go through the WHQL signing process. But even if they do, we've learned that trusting their content (which was all zeros in this case) didn't go well.Why it's here

Well in link to this video that was posted above, are good explanation
They loaded code dynamically and this file with code was all zeroes which they didn't check
So there is no way rust will help here
That modern developers community... probably they better should make coffee for engineers
