The U.S. intelligence community and the Pentagon have quietly agreed on the outlines of an offensive cyber attack that the United States would unleash if Russia electronically interferes with the 2018 midterm election on Nov. 6, according to current and former senior U.S. officials who are familiar with the plan.

In preparation for its potential use, U.S. military hackers have been given the go-ahead to gain access to Russian cyber systems that they feel is needed to let the plan unfold quickly, the officials said.

The senior official clarified that it would be direct interference – efforts to tamper with voting registration and recording votes – that would bring “swift and severe action.” The reason, the official said, is “that fundamentally wrecks the natural process that we have established in this country.” That official didn’t describe what the U.S. action would be.
