"What the Russians probably want to make the election seen illegitimate. So, they are stealing documents from politicians, from individuals, leaking secrets from around the world. The reason they are doing that is to make democracy seen like a bad system," Christopher Porter, a top intelligence lead from FireEye's iSIGHT team, told PTI.
He said there is "no doubt" that the Russian government is behind these latest cyber hacking into the Democratic party and those of the top officials of the Clinton Campaign.
FireEye is a publicly listed enterprise cybersecurity company that provides products and services to protect against advanced cyber threats such as advanced persistent threats and spear phishing.

"I believe that APT 28 knew that they would be traced back to Russia, when they did the operation and that is kind of trying to send the US Government a message. It is definitely the Russian Government and they wanted the US Government to know about it as well," Porter claimed.
"They can get into companies. They can conduct attack that can disable critical infrastructure like power plants. Their only limit is what the Government is willing to do. They are among the best in the world," he said.
Porter said FireEye has observed Russian interference in elections for many years now.
"This is not a new activity. It is new only in the US. They routinely undertake cyber operations against democracies in Eastern Europe and other neighbors in the region, mostly to effect turnout, to spread propaganda, and to make the election seen less legitimate. We have not seen them directly altering votes and their candidates do not usually win the election even with their meddling," he said.
