The voter registration systems in at least seven states were reportedly penetrated by covert Russian operatives prior to the 2016 presidential election.

Intelligence reports provided to then-President Obama showed that seven state systems — including some actual voter databases — were compromised by Russian operatives, according to NBC News.

The intelligence community believes that hackers were able to enter election websites, voter registration systems and voter look-up systems.

Although some systems were compromised — state and federal officials insisted that no votes had been changed, the report said.

The states impacted were Alaska, Arizona, California, Florida, Illinois, Texas and Wisconsin.

Six of those states have actually denied federal conclusions that they were breached — instead citing their own analysis that had separate results, the network reported. The discrepancy shows the lack of coordination between local and federal officials on defending against cyber attacks.

The information comes to light as federal officials are warning of further cyber intrusions in advance of the 2018 midterm elections.
