Columbia, SC - According to a South Carolina State Election Commission (SEC) April 2017 report, on Election Day, November 8, 2016; 149,832 hacking attempts were made to the state's voter registration system. The SEC submitted the report to the South Carolina House Legislative Oversight Committee.
The report did not provide any evidence that the hacking attempts resulted in any successful breaches into the system, but did identify that the hacking attempts were carried out by automated bots.
The State of South Carolina hired a private cybersecurity firm and also called in the state's National Guard's cybersecurity experts to conduct security assessments at county election offices. The State also requested the assistance of the US Department of Homeland Security which remotely completed a "cyber-hygiene scan" of South Carolina's systems and found 55 vulnerabilities with four (4) Internet-connected devices used by the State Election Commission.
As reported by the Post and CourierExecutive Director Marci Andino advised that while the number of attempts seem high, the number doesn't tell the whole story.
