Manufacturers of voting machines are so worried their machines are insecure that they... tried to stop people testing them.

Voting-machine makers are already worried about Defcon

Last year, Defcon's Voting Village made headlines for uncovering massive security issues in America's electronic voting machines. Unsurprisingly, voting-machine makers are working to prevent a repeat performance at this year's show.
According to Voting Village organizers, they're having a tough time getting their hands on machines for white-hat hackers to test at the next Defcon event in Las Vegas (held in August). That's because voting-machine makers are scrambling to get the machines off eBay and keep them out of the hands of the "good guy" hackers.
Village co-organizer Harri Hursti told attendees at the Shmoocon hacking conference this month they were having a hard time preparing for this year's show, in part because voting machine manufacturers sent threatening letters to eBay resellers. The intimidating missives told auctioneers that selling the machines is illegal -- which is false.
Electronic voting-machine manufacturers and anyone with a stake in keeping their flaws secret have oodles of reasons to prevent Defcon's Voting Village from having a repeat performance of last year's (perfectly legal) mass hacking of e-vote boxes.

Voting-machine makers with anything to hide couldn't have been happy about that. If you remember the headlines after last year's Defcon, the results that came out of the Voting Village were beyond problematic. Shocking, even.
Defcon's hackers breached every single voting machine in the Village. Some in minutes; many in under an hour-and-a-half. E-vote machines were popped by hackers without insider knowledge and by hackers who didn't even specialize in voting machines.
One attendee remarked on Twitter, "Horrifyingly, some were hacked wirelessly (ie no physical access). Many hadn't had OS or basic software patches in over a decade." They added, "Others had been sold off after use, but hadn't been wiped; still had voter data on them. Didn't hear of any with any credible audit trail."
