t’s no secret, given the hacks that have plagued the Democratic National Committee and the Clinton campaign. But security researchers warn that it’s just the beginning. “There’s not even a doubt in my mind that there are other actors out there that have yet to be found,” Crowdstrike CEO George Kurtz told CNNMoney. “I’m sure there will be other hacks that come out over the course of this election and certainly beyond that.” Kurtz, whose firm was brought in by the DNC to investigate the hack, called the hack a watershed moment. He said Crowdstrike has been fielding calls from Washington as political parties wrap their heads around a new type of threat: Hackers trying to manipulate the U.S. election. Far from Washington, hackers descended on Las Vegas to show off their party tricks at Black Hat, the annual conference that puts security on the frontlines. They hacked cars, ATMs and mobile devices. This year, there was a new addition: a simulated version of a hackable electronic voting machine, assembled by security firm Symantec. Brian Varner, a security researcher at Symantec, said the electronic voting machine is another frontier for hackers.
