A hack on an Arizona election database during the 2016 U.S. presidential campaign was carried out by suspected criminal actors and not the Russian government, a senior Trump administration official told Reuters on Sunday. The official was responding to a report on CBS News’ “60 Minutes” citing an internal government document that Russian hackers successfully infiltrated computer systems associated with at least four U.S. states, including Arizona, leading up to the 2016 election. Hackers working for the Kremlin breached systems in Illinois, a county database in Arizona, a Tennessee state website and an information technology vendor in Florida, according to the previously undisclosed Oct. 28, 2016, assessment from the Department of Homeland Security, according to the program.
But an administration official, speaking on condition of anonymity, said media reports had at times relied on outdated or incomplete information and conflated criminal hacking with Russian government activity. The cyber attack on Arizona was not perpetrated by the Russian government, the official said.
Media outlets including Reuters reported in August 2016 that the Federal Bureau of Investigation had detected Russian breaches of voter registration systems in Arizona and Illinois.
