"As far as I am concerned [of] the cyberwarfare that's going on in the world, we are jumping to conclusions without the basis or fact[s], people are saying stupid things and it is easy to blame 'The Russians are coming! The Russians are coming!' over and over," Stone told the RT broadcaster in an interview.
Stone said he had been hearing such claims "all his life" and they are "stupid" and "nothing new." According to the film director, while making the "Snowden" movie, he has learned that it takes a "a lot of time to figure out who did what to who, sometimes months," when it comes to cyberwarfare.
"It is easier to point to the enemy as the instigator of the leak," Stone said.
Stone said that the breach, which had resulted in resignation of several DNC staff members, concealed the fact that the DNC officials had taken measures to hamper Sanders' nomination in "supposedly democratic society,"
He added that the fact that an insider could have been behind the leak was also possible.
In July, Kremlin spokesman Dmitry Peskov dismissed allegations of Russian involvement in the DNC cyberattack as "absurd," saying it was an attempt to "manically use" the issue of Russia in the US electoral campaign.
