The investigators found evidence of extraneous interference in the work of the site of local elections in Tennessee. This site posted data on the results of the first round of elections, CBS reports.
As the investigators established, during the general cyber attack, which was the likely cause of the termination of the site operation, Ukrainian IP-addresses were involved. The company Sword & Shield Enterprise Security specifies that on May 1, the site had users from a "suspiciously large number of countries" - more than 100 worldwide.
"Given the suspicious activity and especially proven simultaneous malicious interference with IP-addresses from Ukraine ... I consider it expedient to put forward a hypothesis that this was deliberate action," said the deputy director of information technology in the county of Knox.
He also said that the voting data was not affected, but the site did not work within an hour after the closure of the polling stations.
Experts also expressed concern that other states can use such attacks to reduce the credibility of democratic processes in society.
The director of technology and information of the county Richard Moran said that although the traffic came from foreign servers, this does not mean that the organizer of the attack was abroad. Dan Wollech, a professor at Rice University, stressed that the attackers could quite well hack into computers and launch attacks from them anywhere.
