The Romanian hacker who first inadvertently revealed the existence of Hillary Clinton’s secret, off-the-books email account back in 2014 now says he directly breached her home server, contradicting claims to the contrary by the Clinton campaign.

In a prison interview with Fox News, Guccifer—whose real name is Marcel Lehel Lazar—claims it was “easy” to breach Clinton’s server after compromising an email account belonging to her friend and adviser, Sydney Blumenthal:

The 44-year-old Lazar said he first compromised Clinton confidant Sidney Blumenthal’s AOL account, in March 2013, and used that as a stepping stone to the Clinton server. He said he accessed Clinton’s server “like twice,” though he described the contents as “not interest[ing]” to him at the time.

“I was not paying attention. For me, it was not like the Hillary Clinton server, it was like an email server she and others were using with political voting stuff,” Guccifer said.

Guccifer’s technical explanation is light on details—essentially he traced the server’s IP address from emails Hillary sent to Blumenthal’s account—but plausible:

Lazar emphasized that he used readily available web programs to see if the server was “alive” and which ports were open. Lazar identified programs like netscan, Netmap, Wireshark and Angry IP, though it was not possible to confirm independently which, if any, he used.

This completely contradicts statements from Hillary Clinton and her campaign about the integrity of her email server, which has boiled over into a scandal of national scope. On a portion of her website dedicated to answering questions about the server, Clinton’s campaign says the following:

Was the server ever hacked?

No, there is no evidence there was ever a breach.

Was there ever an unauthorized intrusion into her email or did anyone else have access to it?

No.

Of course, at this point there’s no way to verify any of Guccifer’s claims, nor has he provided a single piece of evidence to support them. It’s also worth keeping in mind that Guccifer’s fate is currently resting upon his continued cooperation with the FBI, and of course, the more important they think Guccifer may be, the better for Guccifer—he’s told Fox that he still has “two gigabytes” of unreleased, hacked material.
