We have our graduation test in about a week, although I won't be hacking (cuz the test is easy as hell) I found out that it wouldn't be to hard to hack... A few hours of programming, yeah, but nothing trivial.
They have it so the internet plug in is off... making it so that you have no connection to the internet on these shitty macs. But the school has 24-7 wi-fi (no pass-word req.). The computer you're on lacks the use of a normal web browser... So, what do you do?
Easy. Grab a connecting piece (that you put on computers to access the internet (think laptops)), jam that it. Since the schools wi-fi is unprotected... You're in. You jam in your Flash drive which holds a .swf file. This file is a in flash browser (which.... mind you... would take FOREVER to make, beside the point

) You use this to log into VZWpix.com (Verizon Pics website) log in to your number, and send info using the internets cell-phone thing. Annoyingly, cell phones are prohibited during the test (lol) Which makes it nearly impossible (if not impossible enough) But if you could, hack a cell phone so it reads the messages in electrical jolts, then has a long pause or a long jolt to signify that the message is over.
Also another impossible factor... You don't have the answers.... Of course, if a test mattered that much, you could go all LC4 over the asses of the company that made the test.. Or just get an in-man.
Now all that happening for a test this easy? Not likely, but sure is fun to think about, right? ;D
