Allegations of a data breach at Bitfinex surfaced on social media on April 26, fueled by a tweet from Alice at Shinoji Research. The tweet, shared and amplified by Walter Bloomberg, claimed that Bitfinex had been hacked by the FSociety hacker group, compromising the personal data of 400,000 users along with 2.5 terabytes of information. Bitfinex's CTO, Paolo Ardoino, refuted these claims, asserting that the rumors were untrue and that the exchange's user database remained secure. The claims made were later corrected by Alice from Shinoji Research, clarifying the situation surrounding the alleged breach.
