U.S. military launched over 2 dozen cyber operations before 2020 election

Context: The disclosure of the operations comes a week after the Office of the Director of National Intelligence released an assessment on foreign actors' campaigns to influence the election.

• That appraisal found no indications that foreign actors attempted to alter any technical aspect of the U.S. voting process.

What they're saying: U.S. Cyber Command in recent months attempted to mitigate the threat to federal systems from the SolarWinds breach by Russian-backed hackers that became public in December 2020, Nakasone added.

• "To date, we have yet to identify any compromise of DoD information networks in the unclassified or classified domains," he said, though the command is still monitoring for affected systems.
• He described the SolarWinds Breach as “a scope, a scale, a level of sophistication that we haven’t seen previously.”

The big picture: President Biden last December promised to impose "substantial costs" on those responsible for the Solarwinds attack, though his administration has yet to describe how exactly it plans retaliate.
