There is no such thing as hacker proof anything. Nothing at all. I can guarantee you that every computer in the world can be hacked, so long as the hacker can get access to it. But these idiots were determined to give it a shot, so they tried a one week experiment where they put the system online and told hackers to go at it. Mind you, no real votes were being cast; they just wanted to see if anyone could hack it.
Within a few days someone managed to make it so that every time you cast a vote, the University of Michigan fight song played.
Honestly, I think the city of Washington, D.C. should ask the hacker to come forward and give him a medal. He or she showed all of them it was a waste of time to put voting online.
Now if only they could get equally smart about electronic voting machines. Hey, any hackers want to harmlessly hack their system just to show how vulnerable it is? Like making it play a song after every vote is a perfect example of patriotic hacking. Someone needs to show these people you can’t trust these machines.
