i think that alot of people would like somthing like this. But i dont think its made yet. If you want to hack into your school database then there are a couple of ways:
1. Put a keylogger on a teachers/faculty computer in order to gain the password/username to login. Then login (recommend being somewhere public so that you wont get traced as easily) and do what you want.
2. Social Engineering, figure out the website URL to login to the admin database, call up the IT desk and pretend to be working on the computers database and make them tell you the password.
3. Phishing, create a fake website or a URL redirector that will send to a page you made that looks the same as the login but will send you the info, display a login error, and redirect them to the regular page.
4. Shoulder surfing, if you can get behind a teacher when they are logging in and sneek a peek at the password, do so. This is probaly the least likely way.
5. Trojan, plant a trojen on there computer that will act just like a keylogger to steal there info, maybe some extra info while your at it
6. Straight up hacking, hack into there database. Takes alot of work if you have to idea how to do it (like me) but you would have to mess around with the login identification and figure out a way to crack it.
Well here are some ways you could go about doing this. I take no responsibilty though in anything you choose to do. And if this is against the Forums rules then please delete this post.
Thanks and hoped I helped out alittle.
