The database of the Japanese unit of the bankrupt cryptocurrency book FTX with confidential information has been posted on the network, Cybernews experts found out.

The discovered database contains 26 million files with logins and user names, e -mail and postal addresses, as well as with FTX records identifiers. Information on loans, cryptocurrency transactions, pledges and marginal rates is also published. Cybernews experts noticed that the files are relatively fresh, some transactions logs were created in July 2024, despite the fact that the FTX was closed from the end of 2022.

In February 2023, FTX Japan completed the bankruptcy and withdrawal procedure. However, apparently, her bacand system remained active until the end of 2024, they suggested at Cybernews. After the collapse of the FTX, the Japanese subsidiary was acquired by the Bitflyer Holdings group, and in 2024 the FTX Japan was renamed Custodiem.

It is unclear whether the detected leak is related to the actively used Custodiem infrastructure or is an “abandoned artifact” remaining after the collapse of the FTX, Cybernews specialists doubt.

There are fears that cybercriminals can use this information for attacks on FTX users. In recent months, the number of phishing attacks has become more frequent, when scammers send to people emails, posing as large companies. Data leak also causes concerns about confidentiality and compliance with regulatory requirements. According to Japanese laws, cryptocurrencies are required to comply with security standards, so the organization may undergo pressure from the regulators and even get a fine.

In May, it became known about the leak of personal data of about 1 million users of the American crypto -tank Coinbase. Similar facts of leakage of confidential information expose crypto services to the risks of physical violence.
