US off-off-year elections go off without noticeable difficulty.
The highly diversified and decentralized US election system kept a close eye on Tuesday's off-off-year elections and has more-or-less declared success, as a joint announcement from several Federal law enforcement and intelligence agencies asserted that election security had been “unprecedented.” That announcement did, however, note that attempts to influence or interfere with the 2020 elections could be expected to continue, with Russia, China, and Iran likely to be particularly active.
The concerns officials are voicing continue to focus on influence operations as opposed to direct manipulation of vote totals or other attacks on voting machinery. CISA Director Christopher Krebs told CBS News no one should get cocky. Speaking of Russian operators in particular, Director Krebs said, "They're going to be back. They're trying to get into our heads. They're trying to hack our brains, so to speak, and ultimately have us — lose faith in our processes."
Some private sector experts agree. FireEye CEO Kevin Mandia told CNBC's Mad Money that the biggest problem with election security isn't hacked voting machines, but rather misinformation disseminated over social media. Vice reports that disinformation relative to the 2020 elections is already flooding social media, and a study by Freedom House concludes that social media have increasingly become tools of influence operations and social control exercised by illiberal governments.
Direct hacking does remain a concern, however well this week's elections proceeded. McAfee told the Washington Post that many voting machines in swing states remain vulnerable to attack.
