After being extradited in March, Lazar also claimed to have hacked the Democratic presidential candidate’s personal email server, saying "It was easy…It was like an open orchid on the Internet."
Lazar, who also used the names "Guccifer Seven,""Micul Fum" and "Marcel Lazar Lehel," claimed that when he accessed Blumenthal’s email, he found correspondence from Clinton, and used that information to gain access to an unsecured server used by the former Secretary of State. Lazar said that he was unimpressed with what he found.
"It was not what I was looking for. It was boring stuff."
According to court documents, Lazar "knowingly devised and intended to devise a scheme to defraud the victims below, and to obtain money and property by means of materially false and fraudulent representations, pretenses and promises, and, for the purposes of executing such scheme, transmitted by means of wire communications in interstate commerce certain writings, signs, signals, and sounds."
The document also states that Lazar breached a Facebook account to post messages like, "You will burn in hell Bush!" and "Kill the illuminati! Tomorrow’s world will be a world free of illuminati or will be no more!"
Brian Fallon, a presidential campaign adviser for Clinton, denied these claims, saying, "There is absolutely no basis to believe the claims made by this criminal from his prison cell. In addition to the fact that he offers no proof to support his claims, his descriptions of Secretary Clinton's server are inaccurate. It is unfathomable that he would have gained access to her emails and not leaked them the way he did to his other victims."
Fallon went on to say that, "We have received no indication from any government agency to support these claims, nor are they reflected in the range of charges that Guccifer already faces and that prompted his extradition in the first place. And it has been reported that security logs from Secretary Clinton’s email server do not show any evidence of foreign hacking."
Lazar, a 44-year-old taxi driver, was first indicted in 2014 on nine counts of computer crimes, each stemming from gaining illegal access to individual accounts belonging to celebrities and prominent figures in American politics, including former Clinton adviser Blumenthal, Dorothy Bush Koch, sister of former President George W. Bush and daughter of former President George H.W. Bush, Jim Nantz of CBS Sports, author Candace Bushnell and former Secretary of State Colin Powell.
Clinton’s email server is included in an ongoing federal investigation to learn whether classified information was stored illegally by the candidate while she was the US’ top diplomat.
Last month the hacker pleaded not guilty to obstruction of justice, cyberstalking and unauthorized access to computers charges.
Lazar is scheduled for a change of plea hearing in Alexandria, Virginia, federal courts this Wednesday.
