Bitfinex chief technology officer Paolo Ardoino is casting skepticism on claims circulated on social media that the exchange was the subject of a large-scale data breach, as hacking group FSOCIETY claimed on April 26. 

"We're performing deep analysis of our systems and no breach was found currently," Ardoino wrote on X, noting that fewer than a quarter of the email addresses supposedly stolen from Bitfinex's servers match legitimate users. 

Hacking group FSOCIETY, styled after the fake hacking group from the television show Mr. Robot, claimed successful hacks on several victims on its darkweb homepage on April 26, including Rutgers University, consulting firm SBC Global, and crypto exchange "Coinmoma," likely a misspelling of Coinmama.
