Lol I remember back in the day when we used to replace the windows logo during boot with our own bitmaps (if I can appropriately remember the file format) at school. We showed kids and suddenly every computer was booting with unexpected media. Admins were not pleased.

But the real fun began when we showed people how to set bios passwords and that cascaded into kids rendering an entire classroom of computers unbootable.

And then there was the time I thought I was really clever because I realized I could open arbitrary files in notepad, so I attempted to edit save files for a learn-to-type program by replacing the score with my own. It seemed to work so I told my friends and then they started copying the same save file into their program files. I don't remember exactly what happened, but I do know the UI update did not propagate to the actual scores and also it introduced a bug into the prodgram which would cause it to crash at distant future epochs, so we destroyed the program for everyone, not just our user profiles. There was an investigation and I think they gave up because the same bad file somehow was on everyone's computer and everyone just told them they got the file from someone else and there was no root of the chain.

This is all to say, any bypass will be identified and implemented at the speed of virality.
