US warns of last-minute Iranian and Russian election influence ops

U.S. CISA, ODNI, and the FBI warn that Russian and Iranian actors are conducting last-minute influence operations targeting the U.S. election, including fabricated videos, fake articles, and impersonation of the FBI to sow distrust, suppress turnout, and incite tensions—particularly in swing states. Authorities cite specific false narratives (e.g., claims of ballot stuffing, fake overseas ballots, and rigged inmate voting) and reiterate that while DDoS activity against election infrastructure may increase, it is not expected to impact the integrity of the election; CISA also reaffirmed support to state and local election officials.
