Surkov leaks

In October 2016, Ukrainian hacker group CyberHunta leaked over a gigabyte of emails and other documents alleged to belong to Russian political operative and senior Kremlin official Vladislav Surkov. Known as Russia's "grey cardinal", Surkov serves as a political adviser to President Vladimir Putin and is the architect of Russia's ideology of sovereign democracy.

The document leak included over 2,300 emails from Surkov's inbox. The emails illustrate Russian plans to politically destabilize Ukraine and the coordination of affairs with major opposition leaders in separatist east Ukraine. The release included a document sent to Surkov by Denis Pushilin, former Chair of the People's Soviet of the Donetsk People's Republic, listing casualties that occurred during 2014. It also included a 22-page outline of "a plan to support nationalist and separatist politicians and to encourage early parliamentary elections in Ukraine, all with the aim of undermining the government in Kiev."

The Kremlin has said that the leaked documents are fake.

Washington think tank Atlantic Council's Digital Forensic Research Lab conducted an analysis of the emails. They determined that they were genuine, based partially on the routing information. Russian entrepreneur Yevgeny Chichvarkin confirmed that his emails from the document dump were authentic, saying "Yes, this is my original text." Russian journalist Svetlana Babaeva also verified that her three emails from the leak were genuine.

Kremlin press secretary Dmitry Peskov suggested that the emails did not belong to Surkov, saying that he "does not use email." Oleksandr Tkachuk of Security Service of Ukraine stated that they had managed to "authenticate a number of documents in the release" but could not confirm the authenticity of the entire batch of documents.
