DEFCON is where hackers and pentesters come together to show off their skills at breaking security and on tap this year will be various teams trying their hands at voting machine hacking.

Hackers at DEFCON 25 are expected to try to crack voting machines from a number of angles. Some will attempt remote attacks on electronic voting machines, some will analyze hardware for flaws and others will look into potential voting machine hacking from the perspective of an attacker with physical access looking to affect individual machine results.

Before the 2016 U.S. presidential election there were reports of multiple hacks of state voter databases, security experts feared potential voting machine hacking during the election and the White House even warned Russia about it.

Jeff Moss, founder of DEFCON, told Politico that it was clear voting machine hacking was a topic that needed to be investigated given the news surrounding Russia's intentions to affect the 2016 U.S. presidential election. Moss said the DEFCON 2017 organizers are still in the early stages of planning, including locating used voting machines for the testing.

Neither Moss nor DEFCON officials responded to requests for comment, but Matthew Masterson, chairman of the U.S. Election Assistance Commission (EAC), offered to help.

Masterson said the EAC is "focused on helping state and local election officials carry out accurate, accessible and secure elections."

"Our door is always open to DEFCON organizers and anyone with the goal of improving the U.S. election system. The EAC is constantly looking for ways to improve U.S. voting system security and testing guidelines, so communicating with DEFCON could be very informative for us and equally informative for them," Masterson told SearchSecurity. "We've advised everyone from the Department of Homeland Security to the FBI about the inner workings of our nation's election systems. We would be happy to provide that same kind of soup to nuts expertise to DEFCON organizers."

The DHS refused to provide a comment for this story.
