Military cyber officials are developing information warfare tactics that could be deployed against senior Russian officials and oligarchs if Moscow tries to interfere in the 2020 U.S. elections through hacking election systems or sowing widespread discord, according to current and former U.S. officials.

One option being explored by U.S. Cyber Command would target senior leadership and Russian elites, though probably not President Vladimir Putin, which would be considered too provocative, said the current and former officials who spoke on the condition of anonymity because of the issue’s sensitivity. The idea would be to show that the target’s sensitive personal data could be hit if the interference did not stop, though officials declined to be more specific.

“When the Russians put implants into an electric grid, it means they’re making a credible showing that they have the ability to hurt you if things escalate,” said Bobby Chesney, a law professor at the University of Texas at Austin. “What may be contemplated here is an individualized version of that, not unlike individually targeted economic sanctions. It’s sending credible signals to key decision-makers that they are vulnerable if they take certain adversarial actions.”
