E-voting machines and voter registration systems used widely in the United States and other countries’ elections can readily be hacked—in some cases with less than two hours’ work.

Some of those hacks could potentially leave no trace, undercutting the assurances of election officials and voting machine companies who claim that virtually unhackable election systems are in place.
