How hackers are trying to cast their ballots for president this election season

As Americans head to the polls on Election Day, are hackers also preparing to vote? Some security researchers have found vulnerabilities with the machines some Americans will use to vote. The news comes in a hotly contested election cycle where hacked emails are being deployed furiously in an attempt to sway public opinion. Meanwhile, hackers have already tried to breach election systems in more than 20 states, according to the Department of Homeland Security. According to experts, the people doing the hacking may not have to try hard. The machines themselves physically have been shown to be very vulnerable," Cris Thomas, a strategist for Tenable Network Security, a Maryland based cybersecurity company, told CNBC's "On the Money" recently. In a related development, some machines are using outdated technology. "The fact is we've been voting on old technology, old Windows 2000 based operating systems… The voting machines themselves are archaic having been around for 10-15 years," said Congressman Hank Johnson, a Georgia Democrat who has sponsored legislation on the issue.
