The U.S. government has concluded that Iran is behind a series of threatening emails arriving this week in the inboxes of Democratic voters, according to two U.S. officials.
Department of Homeland Security officials told state and local election administrators on a call Wednesday that a foreign government was responsible for the online barrage, according to the U.S. officials and state and local authorities who participated in the call, all speaking on the condition of anonymity because of the matter’s sensitivity.
A DHS officials also said they had detected holes in state and local election websites and instructed those participating to patch their online services.
The emails claimed to be from the Proud Boys, a far-right group supportive of President Trump, but appeared instead to be a deceptive campaign making use of a vulnerability in the organization’s online network.
