WASHINGTON (Reuters) – Wisconsin, Ohio and several other states said on Friday they were among 21 states that Russian government hackers targeted in an effort to sway the 2016 presidential election in favour of Donald Trump though no votes were changed.
The Department of Homeland Security confirmed it had notified the states of the activity but declined to identify them. Russia has denied election meddling, and President Trump has denied any collusion with Russia.
Alabama, Colorado, Minnesota, Connecticut and Washington State also confirmed they were targeted by Russian hackers but said they were not successful.
“There remains no evidence that the Russians altered one vote or changed one registration,” said Judd Choate, president of the U.S. National Association of State Election Directors.
Wisconsin Elections Commission Administrator Michael Haas said Homeland Security told the states that “Russian government cyber actors” targeted state voter registration systems.
DHS officials have said that in most of the 21 states only preliminary activity was observed from hackers and a small number of networks were compromised. Some states had complained in June they had no idea if Russians had attempted to infiltrate their systems.
U.S. intelligence agencies have concluded the Kremlin orchestrated an operation that included hacking and online propaganda intended to help Trump win, Reuters reported in August.
Colorado Secretary of State Wayne Williams said DHS told it that its systems were scanned in the weeks before the 2016 election. “A scan is similar to burglars jiggling the doors of a house and moving on when they realise the doors are locked,” the state said.
Minnesota Secretary of State Steve Simon said entities at the Russian government’s behest scanned the state’s system for vulnerabilities but did not breach the system.
A spokesman for Connecticut’s secretary of state said Russian intruders were detected and blocked.
Washington State’s top election official, Kim Wyman, said the state learned in 2016 of attempted intrusions from Russian internet addresses and immediately alerted the FBI.
Arizona and Illinois confirmed last year that hackers had targeted their voter registration systems, but Wisconsin said in recent months it had no idea if it was targeted.
Homeland Security told Wisconsin that the Russian government tested election systems for vulnerabilities in hopes of accessing voter registration databases but was unsuccessful,…
