Key Findings
- A Russian government subcontractor employee has leaked thousands of documents detailing Russia’s cyberwarfare capabilities.
- The leaked files, now called the Vulkan Files, have drawn comparisons to the immensity and importance of the documents leaked by Edward Snowden in the United States in 2013.
- These files demonstrate the Russian government’s focus on its cyberwarfare capabilities and its multilayered approach to advancing these capabilities.
- The Vulkan Files likely diminish the ability of the Russian government to utilize plausible deniability to distance itself from cyber actions that have taken place in parallel with its military actions.
