An article by Lisa Vaas at Naked Security:

It’s still child’s play to pick apart election systems that will be used in the 2020 US presidential election, as ethical hackers did, once again, over the course of two and a half days at the Voting Village corner of the DefCon 27 security conference in August.

The results are sobering. This is the third year they’ve been at it, and security is still abysmal.

On Thursday, Voting Village organizers went to Capitol Hill to release their findings, in an event attended by election security funding boosters Sen. Ron Wyden and Rep. Jackie Speier.

In a nutshell: in August, hackers easily compromised every single one of the more than 100 machines to which they were given access, many with what they called “trivial attacks” that required “no sophistication or special knowledge on the part of the attacker.” They didn’t get their hands on every flavor of voting system in use in the country, but every one of the machines they compromised is currently certified for use in at least one voting jurisdiction, including direct-recording electronic (DRE) voting machines, electronic poll books, Ballot Marking Devices (BMDs), optical scanners and hybrid systems.
