Cryptocurrency exchange Binance rejected accusations of a possible leak of user data and stated that the exchange’s client security systems function without failures.

A blockchain network researcher under the nickname @otteroooo informed followers of his blog on social network X that he had discovered an offer to sell the Binance user database on the darknet. @otteroooo associated the fact of selling confidential information with a possible leak and publication of the Binance program code on the GitHub platform.

Later, these suspicions were confirmed by another user of the X network under the nickname @cryptonator1337, who discovered several more similar offers.

In response to the allegations, Binance customer support thanked bloggers for their vigilance and information about potential risks. Binance added that the exchange’s security service does not confirm the data leak and all user accounts remain secure. Exchange representatives noted that user accounts are protected in a variety of ways, including multi-factor authentication and biometrics, which makes unauthorized access impossible.

404 Media previously reported that highly sensitive cache code, infrastructure diagrams, internal passwords and other information belonging to Binance had been publicly available on GitHub for several months.
