I am not surprised that hackers managed to get into celebrities iClouds. With new technology, and relied use on the internet it is possible to get into anything. No account is 100% safe from hackers. Most people, however, don't think a lot about what they are posting or saving to this accounts. I am guilty of this as well. I think most people are.
     In my opinion, the hackers should be prosecuted. They probably never will be, but it was illegal and should be taken seriously.
