The man who revealed the Hillary Clinton email scandal was sentenced on Thursday to 52 months in prison for unauthorized access of a protected computer, and aggravated identity theft.

Marcel Lazar, a former Romanian taxi driver, would hack the internet in his spare time, under the handle of "Guccifer."

Lazar, who does not have any training in computer programming, managed to breach the security of more than 100 US email accounts - including that of Clinton senior advisor Sidney Blumenthal.

The 44 year-old was arrested in Romania in 2014, after targeting the Bush family and former US Secretary of State Colin Powell.

Other victims included the head of the US National Intelligence Council, Christopher Kojm, and the creator of hit drama show Downton Abbey, Julian Fellowes.

The amateur hacker leaked confidential information about several high-profile victims - including Blumenthal's emails with Clinton, which first drew attention to the fact that she was using her private email server in upstate New York to send classified State Department material.

Lazar, who was extradited from Romania to the United States, did not address the court at his hearing on Thursday. He was sentenced to 52 months in prison.

His legacy, though, lives on: In June, a hacker who goes by the alias "Guccifer 2.0," claimed data breaches on the Democratic National Committee and the Democratic Congressional Campaign Committee.

US intelligence officials believe Guccifer 2.0 is linked to Russian intelligence services, suggesting that the hack was sponsored by the foreign state.

There is no known connection between Lazar and Guccifer 2.0.
