Voting Machine War Games

This is still an issue. (WaPo)

To determine what it would take to hack a U.S. election, a team of cybersecurity experts turned to a fictional battleground state called Pennasota and a fictional gubernatorial race between Tom Jefferson and Johnny Adams. It's the year 2007, and the state uses electronic voting machines.....

The experts thought about all the ways to do it. And they concluded in a report issued yesterday that it would take only one person, with a sophisticated technical knowledge and timely access to the software that runs the voting machines, to change the outcome.
