What laws are broken when you hack someone?

it depends

Explanation:

if you are hacking for a purpose that is benefiting the person being hacked, that is ethical hacking. ethical hacking is not illegal, as long as you get permission from the person being hacked.

if you hack someone without their knowledge, that is unethical hacking, and that is in many cases, a crime, and if it has enough of a detrimental effect on a companys process, it could land you into prison and earn you a hefty fine.

ethical hacking is good for testing a networks security, and if all is well, the ethical hacker shouldnt be able to get into a network if it is secured properly.
