How Likely is an Election Day Hack?

FRISCO - There's a lot of talk of a hack attack by the Russians on election day. But how big of a hack would it take to pull off a voter invasion at the polls?

“It would have to be a huge operation, very well coordinated. There would have to be insiders involved,” said Keith Barthold of DKB Innovative.

DKB Innovative specializes in IT services and security. Barthold says hacking voting booths would be quite a chore. “In order to sway an election or change votes, someone would have to go in with a screwdriver, and potentially swap out the memory."

But a Princeton professor and his students found a way to change ballots in minutes. They bought old voting machines that are still used in some states, to do their hacking. “They were able to attack those and rewrite the software and change how they’re tabulated. But again that required a screwdriver and swapping out a memory card," said Barthold.

So chances are, if you’ve already voted this election, your vote won’t switch because of a hack attack.
