Hackers target voter-registration systems•

washington» Hackers have targeted the voter registration systems of more than 20 states in recent months, a Homeland Security Department official said Friday.

The disclosure comes amid heightened concerns that foreign hackers might undermine voter confidence in the integrity of U.S. elections. Federal officials and many cybersecurity experts have said it would be nearly impossible for hackers to alter an election’s outcome because election systems are very decentralized and generally not connected to the internet.

It was unclear, the official said, whether the hackers were foreign or domestic, or what their motives might be. The Associated Press
