PHILADELPHIA (CBS) — The Department of Homeland Security is urging state election boards to use cyber security resources and experts to guard themselves against any possible attacks during this election season.

A recent report released by a cyber security group this week named Pennsylvania the most vulnerable.

In the report, cyber security firm Carbon Black said most counties in Pennsylvania have older voting machines and cannot be audited. 

David Thornburg is CEO and President of election watchdog group, The Committee of Seventy, he said the machines in PA are made simple.

“Most of our machines are touch-screen machines that don’t have leave a paper trail.”

Thornburg said he thinks an attack is unlikely, because Pennsylvania machines are not connected to the internet.

“Voters should be confident that there aren’t really openings for massive fraud.”

The non-profit, non-partisan group will have a hotline set up for any suspicious activity on Election Day.

“Some of the agitation here is stirred up by folks that provide cyber security services.”

The Department of Homeland Security says so far, 21 states have already reached out to them, to help secure their systems.
