The school isn't going to respond like you seem to believe they will. They will suspend/expell you, and possibly press criminal charges. It's a terrible idea. When you hear of successful greyhats, if you notice, they always report the problem digitally, to dodge these legal issues, or don't actually commit any illegal act. You are doing neither.

Beyond this, you also lack the expertise to pull it off. If you have to ask for help RATing any system at all, you shouldn't be doing anything even remotely risky.
