MADISON, Wis. — The Latest on Wisconsin election security (all times local):

3 p.m.

The U.S. Department of Homeland Security says Wisconsin’s voter registration system was unsuccessfully targeted by Russian hackers.

Wisconsin was one of 21 states notified Friday of the attempted hacking. Wisconsin Elections Commission administrator Michael Haas says the attempted hack had no effect on Wisconsin’s systems or the outcome of the election.

Haas says security provided by the state successfully protected Wisconsin’s systems. And he says the Department of Homeland Security confirmed there was no breach or compromise of Wisconsin’s data.

The state Elections Commission says DHS told it that Russian hackers scanned Wisconsin’s internet-connected election infrastructure likely seeking specific vulnerabilities such as access to voter registration databases.

Haas says he is seeking more information from Homeland Security.

Wisconsin elections officials are putting together a formal security plan in advance of next fall’s election.

The Wisconsin Elections Commission plans to work together with federal, state and local elections officials on the plan to prevent any security breaches. The move comes as federal investigators, and the Senate Judiciary Committee, investigate Russia’s meddling in the 2016 presidential election.

Wisconsin election officials have repeatedly said there were no indications that state elections had been tampered with last year.

Wisconsin Elections Commission assistant administrator Meagan McCord Wolfe says the state is creating the security planning team to prepare for 2018 and in response to the ongoing national conversation about election security.

A draft is expected to be done in December with a final plan to be done in early 2018.
