Russian Hackers ‘Successfully Penetrated’ Voter Rolls In Several U.S. States: Report

A U.S. cybersecurity official confirmed to NBC News Wednesday that Russian hackers “successfully penetrated” the voter rolls in a small number of states in 2016.

Jeanette Manfra, the head of cybersecurity at the Department of Homeland Security (DHS), revealed that Russia targeted 21 states and “an exceptionally small number of them were actually successfully penetrated.”

Twenty-one states were previously notified by DHS that Russia had attempted to hack their elections systems before the 2016 presidential election.

Alabama, California, Colorado, Wisconsin and Florida are among the states that have publicly confirmed they were targeted.

U.S. officials insist there is no evidence any of the voter rolls were altered prior to the election.
