The notorious Romanian hacker known as Guccifer has bragged about how simple it was to access Hillary Clinton’s personal email server.

“It was like an open orchid on the internet,” he told NBC News in an interview aired Wednesday. “There were hundreds of folders.”

Guccifer, whose real name is Marcel Lehel Lazar, is now in US custody. He spoke to NBC from a prison in Bucharest before being extradited.

He claimed that the former secretary of state’s email server was “completely unsecured.”

On Wednesday, speaking from a Virginia prison, he told Fox News that he accessed Clinton’s email by tracking other political heavyweights, including Gen. Colin Powell, Clinton adviser Sidney Blumenthal and members of the Bush family.

“For example, when Sidney Blumenthal got an email, I checked the email pattern from Hillary Clinton, from Colin Powell, from anyone else to find out the originating IP,” he said.

Fox said investigators probing Clinton’s email setup intend to question Lazar about his alleged access to the server.

Clinton’s server held nearly 2,200 emails that contained information now deemed classified — and 22 that were labeled “Top Secret.”

A spokesman for Clinton told NBC that there is no reason anyone should take Guccifer’s claims seriously.

“There is absolutely no basis to believe the claims made by this criminal from his prison cell,” said Brian Fallon, national press secretary for Clinton’s presidential campaign.
