“In each of these stories, we sought to give you, the reader, an in-depth look at these threat actors and their distinct TTPs. In this piece, we build on those reports, drawing from recent congressional testimony, published cybersecurity research and expert commentary to provide you with a profile for each major U.S. cyber adversary. In doing so, we hope to have created a concise introduction and convenient reference to the distinct motives, narratives, strategies, capabilities and operations of each of nation-state threat actor. We also think the similarities, where they exist, will be insightful.”
