Russian hackers “successfully penetrated” some state voter rolls in 2016, the Department of Homeland Security announced this week. One of those state was Illinois where hackers gained access to information such as names, driver’s licenses and partial Social Security numbers on 15 million people. As many as 90,000 records were compromised. As Illinois prepares for its midterm primary on March 20, the elections director for Cook County – containing Chicago – says one of his main concerns is that while cyber attacks have become more sophisticated, our voting infrastructure hasn’t. Noah Praetz joins Soledad O’Brien from Chicago to discuss the steps local election officials can take and why he says perfect cyber defense is not possible.
