In response to the allegations, Tether CEO Paolo Ardoino, who can be the Bitfinex CTO, took to X to deal with the state of affairs immediately
“Everybody panicking for a possible database breach on bitfinex. Tldr: appears faux,” Ardoino posted on social media.
However, in line with Shinoji Analysis, F Society has uploaded a web page on their onion website, accompanied by two Mega hyperlinks resulting in a textual content file containing a partial dump of usernames and plaintext passwords.

Most of customers sadly use identical e mail/passwords throughout a number of websites.”
Bitfinx is conducting a “deep evaluation” of its programs and “no breach was discovered presently,” Ardoino added, calling it “pure FUD.”
