A hacker doesn't deliberately destroy data or profit from his activities.

Think about it: if you were running a multi-million dollar company, and your database of customer information was stolen, would you want to tell your clients? No. Most companies did not until the laws required them to. It's in the best interest of organisations - when they're attacked and information is stolen - to tell nobody.

If I needed to know about a security exploit, I preferred to get the information by accessing the companies' security teams' files, rather than poring over lines of code to find it on my own. It's just more efficient.
