FBI says foreign hackers penetrated state election systems

The bulletin does not identify the states in question, but sources familiar with the document say it refers to the targeting by suspected foreign hackers of voter registration databases in Arizona and Illinois. In the Illinois case, officials were forced to shut down the state’s voter registration system for 10 days in late July, after the hackers managed to download personal data on up to 200,000 state voters, Ken Menzel, the general counsel of the Illinois Board of Elections, said in an interview. The Arizona attack was more limited, involving malicious software that was introduced into its voter registration system but no successful exfiltration of data, a state official said.
