From the Document: "Russia has deployed sophisticated cyber capabilities to conduct disinformation, propaganda, espionage, and destructive cyberattacks globally. To conduct these operations, Russia maintains numerous units overseen by its various security and intelligence agencies. Russia's security agencies compete with each other and often conduct similar operations on the same targets, making specific attribution and motivation assessments difficult. Congress may be interested in the various Russian agencies, units, and their attributes to better understand why and how Russia conducts cyber operations."
