Vincenzo Iozzo, a well-known hacker linked to convicted sex offender Jeffrey Epstein, is no longer listed on the website of Black Hat, one of the world’s largest cybersecurity conferences, nor the Japanese security conference Code Blue.

As of Thursday, Iozzo was not visible on the official pages of the review board of Black hat or Code Blue. He was still listed on two pages last week. Iozzo has been on the Black Hat review board since 2011, according to his LinkedIn profile.

In a statement shared with TechCrunch through a spokesperson, Iozzo said he told Black Hat he was “not ready to resign” and welcomed “a full investigation.”

Black Hat spokespeople did not respond to requests for comment.

Iozzo, currently the founder and chief executive of cybersecurity startup SlashID, has had a long career in the industry. Iozzo wrote one of the first manuals for hackers researching Apple’s mobile software, and in 2015, founded the cybersecurity startup IperLane, which was later bought by CrowdStrike, leading him to serve as the company’s senior director for nearly four years.

Iozzo’s name appears in over 2,300 documents, some of which contain many emailswas released on January 30 as part of a legally required effort by the Department of Justice to publish materials from its investigation into the late financier and sex trafficker.

Iozzo’s interactions with Epstein spanned from October 2014 to December 2018. In late 2018, the Miami Herald published news detailing the allegations that Epstein abused more than 60 womensome of them were teenage girls.

After these stories were published, new ones were released emails are displayed Iozzo tried to meet with Epstein at his home in New York City.

Among the new material published by the Department of Justice, more than 2,300 documents refer to Iozzo, there is also a report from an FBI informant who claimed that Epstein had a “personal hacker.” the DOCUMENTS has been redacted and the alleged hacker has not been named. However, some of the identifying details included in the document strongly suggest that the informant believed Iozzo was Epstein’s hacker. Italian newspaper Places called Corriere della Sera reported on the emails earlier this month and named Iozzo as the person who may have redacted the informant’s document.

It is important to note that the FBI informant’s claims and allegations have not been confirmed by the FBI and may be partially false. Furthermore, there is no evidence in the emails to suggest that Iozzo did anything illegal for Epstein.

Iozzo said in a statement to TechCrunch that he “knew Epstein for professional reasons” and that he wished he hadn’t, but he denied claims that he was Epstein’s hacker or hacked on his behalf.

“We were introduced in 2014 when I was a 25-year-old MIT fundraising for my startup, by people I trust and admire. Because of this, I failed to ask the right questions that, in retrospect, seem obvious,” read the statement, sent by his spokesperson Joan Vollero. “I foolishly accepted the narrative presented to me by others that greatly diminished the magnitude of his horrific actions. I regret the past association and take full responsibility for not using greater judgment at the time.”

“My interactions with Epstein were limited to business opportunities that never materialized, as well as discussions on markets and new technologies. I never observed or participated in any illegal activity or behavior,” added Iozzo.

In 2008, Epstein pleaded guilty to soliciting sex from girls as young as 14 and registered as a sex offender in Florida and New York. In 2018, new reports emerged that Epstein was allegedly a serial sex abuser and trafficked underage girls to his private island. Following these new reports, the Department of Justice formally charged Epstein in 2019 for trafficking, exploiting, and abusing twelve minor girls. Epstein then died in prison.

Neither Iozzo’s spokesman, Vollero, nor his attorney, Emma Spiro, explained why Iozzo was removed from Black Hat’s website, but did not dispute the removal.

“Mr. Iozzo welcomed an independent investigation from Black Hat, rather than a knee-jerk decision, because he was confident that he would be cleared through that process,” Vollero said.

Code Blue spokesperson Ken-ichi Saito confirmed to TechCrunch that the conference has removed Iozzo’s name from its review board. Saito said the conference “has been preparing for this update for months” to remove Iozzo and two other review board members as “inactive” and that the “timing of our website update coincidentally overlapped with the public release of the Epstein documents.”
