Foreign hackers were able to gain access to voter-related information in four states by targeting not only government systems, but also by breaking into computers associated with private contractors hired to handle voter information, ABC News has learned.
As ABC News first reported Thursday, hackers have recently tried to infiltrate voter registration systems in nearly half of the states across the country –- a significantly larger cyber-assault than U.S. officials have been willing to concede.
And while officials have publicly admitted Illinois and Arizona had their systems compromised, officials have yet to acknowledge that information related to at least two other states’ voters has also been exposed.
Hackers working on behalf of the Russian government are suspected in the onslaught against election-related systems, according to sources with knowledge of the matter.
Testifying before the House Judiciary Committee on Wednesday, FBI Director James Comey said his agents are trying to figure out “just what mischief is Russia up to in connection with our election.”
