MacHack

Machack is a term that refers to a person who tries to figure out how to access and control computer systems without permission. It's like when you want to get into a room but you don't have the key, so you try different ways to get in, like climbing through a window or picking the lock. Machack is when someone tries to do this with computers. It's not a good thing to do because it can be illegal and it can even harm the computer or the people who use it.
