In what would be an unusual move for hackers working for the Russian government, a trove of data stolen from Democratic National Committee may have been leaked.

A more than 200-page document that appears to be a Democratic anti-Donald Trump playbook was sent to Gawker by an individual using the alias "Guccifer 2.0." The purported hacker claimed to have about 100GB of data, including "financial reports, donors' lists, election programs, action plans against Republicans, personal mails," taken from the DNC's network, Gawker said Wednesday. The news site said it was also sent a variety of donor registries and strategy files.

Hackers working for the Russian government reportedly broke into the DNC's computer network and gained access to emails, chat transcripts and opposition research on the presumptive Republican presidential nominee. The hackers may have gained access to the network last summer, The Washington Post reported Tuesday, but the committee didn't spot it until research on Trump was taken.

Two different Russian hacking groups targeted the DNC's systems, according to CrowdStrike, the cybersecurity company called in by the Democrats to find the hackers and kick them out.

"CrowdStrike stands fully by its analysis and findings identifying two separate Russian intelligence-affiliated adversaries present in the DNC network in May 2016," the company said in a statement.

"[W]e are exploring the documents' authenticity and origin. Regardless, these claims do nothing to lessen our findings relating to the Russian government's involvement, portions of which we have documented for the public and the greater security community."

"Both adversaries...are believed to be closely linked to the Russian government's powerful and highly capable intelligence services," the firm had previously stated.

The DNC did not respond to a request for comment.
