When the password for a voting machine is “abcde” and can’t be changed, the integrity of our democracy might be in trouble. The Advanced Voting Solutions WinVote machine, dubbed “America’s worst voting machine,” came equipped with this simple password even as it was used in some of the country’s most important elections. AVS went out of business in 2007, but Virginia used its insecure machines until 2015 before dropping them for scrap metal. That means this vulnerable hunk of technology was used in three presidential elections, starting with George W. Bush’s re-election in 2004 to Barack Obama’s in 2012. In addition to Virginia, Pennsylvania and Mississippi used the WinVote without knowing all the ways it could be hacked. Unlike other technology — your phone, your laptop, connected cars — security wasn’t really a focus.
