The Federal Bureau of Investigation (FBI) issued a private industry alert on August 18, 2016, to State Boards of Election to alert them of hackings into Board of Election websites. 

According to the FBI, it “received information of an additional IP address, 5.149.249.172, which was detected in the July 2016, compromise of a state’s Board of Election Web site. Additionally, in August 2016, attempted intrusion activities into another state’s Board of Election system identified the IP address, 185.104.9.39 used in the aforementioned compromise.”

The FBI recommends that states “contact their Board of Elections and determine if any similar activity to their logs, both inbound and outbound, has been detected. Attempts should not be made to touch or ping the IP addresses directly.”

It further outlines precautionary steps that can be taken, which can be accessed here.
