Although I am not familiar with the exact laws, I have heard of many cases which surround the hacking of personal and private information. I would believe that hacking personal information is just as illegal as identity theft (an assumption of course). Therefore, if a person has been hacked, I believe that there must be an legal avenue which they could pursue. I don't see how breaking into a person's computer is any different than breaking into their home (given the amount of personal and private information sometimes stored on computers).
I don't know what the specific laws are surrounding computer hacking, but what I've seen in the news lately has to do with identity theft, business idea theft, and people's personal finances being compromised. In Utah, just a couple of months ago, the Medicaid office in Salt Lake City was hacked and over 800,000 people's social security numbers were hijacked! Personal privacy is a big issue when it comes to people's social security numbers, bank accounts, and children. I think privacy laws are most attacked when someone hacks into a computer system.
