The DNI announced tonight that the FBI believes Iran and Russia are behind the threatening emails being sent to voters in several states. FBI director Chris Wray assured Americans that the election system in the U.S. is safe and has not been compromised by foreign actors.
These emails threaten voters with retaliation if they do not vote for Trump. They have included the voters correct names and addresses causing concern that voting information systems had been compromised; however it should be noted that voter information including addresses, names, and phone numbers, are often public data and easily accessible online. Many other websites provide email addresses for known street addresses, and are often freely available or available for a nominal fee. This information alone is not enough to surmise that Iran, Russia, or any other actor for that matter has compromised any election related system.
