On May 7, 2019, Maj. Gen. Charles L. Moore, the director of operations for Cyber Command, and other Cyber Command officers gave a rare briefing at its new Joint Operation Center.  According to the New York Times:  "American officials deployed last year to Ukraine, Macedonia and Montenegro, and United States Cyber Command officials said that their missions included defending elections and uncovering information about Russia’s newest abilities. Cyber Command will continue some of those partnerships and expand its work to other countries under attack from Russia, officials said Tuesday. The deployments, officials said, are meant to impose costs on Moscow, to make Russia’s attempts to mount online operations in Europe and elsewhere more difficult and to potentially bog down Moscow’s operatives and degrade their ability to interfere in American elections."

In an operation named "Synthetic Theology," Cyber Command took proactive measures to neutralize Russian efforts to interfere with the 2018 U.S. midterm elections by

1. taking offline temporarily the Internet Research Agency, a Russian trollfarm and source of disinformation,
2. sending direct messages to Russians propagating disinformation to identify them, and
3. deploying U.S. officers in Ukraine, North Macedonia, and Montenegro to defend their networks and gather intelligence on Russian activities.  The commander of Cyber Command’s cyber national mission force, Brig. Gen. Timothy Haugh said the U.S. would continue such joint efforts with foreign countries.  [sources: cyberscoop and NYT]
