Mitsubishi UFJ Bank stated that the issue with its online banking system "Mitsubishi UFJ Direct," which began on the afternoon of the 26th, has been resolved. The malfunction may have been caused by a "DDoS attack" that overloaded the server by sending a large amount of data. It is reported that there was no leakage of customer data or virus damage. The bank revealed that the online banking system became unstable around 2:47 PM on the 26th, making it difficult to log in through biometric authentication, among other issues. It was fully restored by the morning of the 28th. Services for businesses also experienced disruptions. (Kyodo News)
