On November 4, GMO Aozora Net Bank released its response to inquiries regarding the cyberattack on a group company. The bank stated that as of the same day, no unauthorized access or information leaks to the bank itself have been confirmed, and there is no impact on accounts or transactions.

This response comes in the wake of a large-scale cyberattack on "Onamae.com Desktop Cloud," a service provided by GMO Internet. Up to 26,739 virtual servers may have been affected, leading to the theft of user login information for transaction accounts and financial damages due to unauthorized transactions. The company was extorted for money by the attackers, and on October 27, data purporting to be users' personal information was publicly released.

On November 2, Masatoshi Kumagai, CEO of GMO Internet Group, apologized at a press conference. He admitted that despite being alerted to system vulnerabilities by an in-group security company, sufficient countermeasures were not implemented, raising widespread concerns about the group's security management system.

Amidst this situation, GMO Aozora Net Bank has also received inquiries regarding deposit safety, information leaks, and compensation. The bank had previously issued a safety announcement on October 27, urging caution due to the spread of misinformation and speculation on social media.

According to the bank, it is a separate entity from GMO Internet, which was attacked, and its systems are independently built and operated. The bank states that its banking systems incorporate multiple layers of defense and have strengthened monitoring systems.

For details on the scope of damage and compensation related to the attacked services, the bank advises users to contact GMO Internet's support desk. Conversely, users who notice any unauthorized transactions are urged to contact GMO Aozora Net Bank, which will guide them through necessary service suspensions and registered information changes.
