U.S. says Iranian hackers behind threatening emails accessed voter data

WASHINGTON (Reuters) - U.S. officials said late Friday that the Iranian hackers behind a wave of threatening emails sent to thousands of Americans earlier this month successfully accessed voter data.

The statement, issued jointly by the FBI and the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA), partially confirms the authenticity of a video distributed as part of a disinformation campaign that briefly drew attention when it became public last week.
