CNN: Voting Machines Easily Get Hacked (2010)
Getting into the machines was as easy as picking a cheap lock.
Princeton researcher Ariel Feldman, showed us one of the hacked machines: "We were flipping votes from one candidate to another to keep the total number of votes the same." And, just to nail the point home about how simple it is to alter the computer's memory card, they replaced the election software with the classic video game, Pac-Man.
"We have found that we can make a voting machine virus that can jump from machine to machine and change the election outcome across a whole state," says Halderman. "This is very, very scary and it's a realistic threat today."
Halderman also found hackers from China and Iran trying to break in.
