Bitfinex, a prominent cryptocurrency exchange, is facing allegations of a data breach by hacker group FSCOIETY.
According to a recent article published by research firm Shinoji Research, Bitfinex has confirmed a cyberattack. It is claimed that the ransomware group Fsociety stole 2.5 terabytes of data belonging to 400,000 customers, including Bitfinex users. The hackers are threatening to leak all user information and KYC data if their demands are not met.
Shinoji Research reported that a user attempted one of the leaked passwords and received a two-factor authentication alert.
CTO’s Response:
In response to the published article, Bitfinex CTO Paolo Ardoino took to Twitter to refute the claims. According to Ardoino, the cybercriminals released a 2-megabyte file containing 22,500 emails and passwords. It was revealed that only 5,000 of these emails were associated with Bitfinex users. Ardoino stated that the alleged cybercriminals had not contacted them and that they would offer a reward if they had genuine information, but no such request had been made.
It was emphasized that the hackers, who are suspected of gathering information from other sources, created an impact due to many users using the same email address.
Ardoino, emphasizing that no breach was detected, advised against believing in FUDs (Fear, Uncertainty, Doubt) and assured that funds were secure.
