Hillary Clinton is warning the technological forces which sabotaged her presidential bid in 2016 are still very much at play.

"I think it's important to learn the real lessons from this last campaign," she said in an interview Wednesday at the Code Conference in California. "The forces aren't just interested in influencing elections and politics. They're going after the economy and our unity as a nation."

Clinton described how a massive Russian-led misinformation campaign scuttled her chances with the help of social networks that aren't properly empowered to combat fake news.

"What we saw in this election particularly the first time we had the tech revolution really weaponised politically," Clinton said. "It was aimed at me but it's a much deeper more persistent effort to literally turn the clock back on so much of what we have achieved as a country."

Clinton also singled out Vladimir Putin for having big ambitions that go way beyond her in his pursuit of destabilising the country.

"It is important that Americans, that people in tech and business understand that Putin wants to bring us down," she warned. "He is an old KGB agent."
