Sony Bank: Digital securities delegate Securitize Japan suffers unauthorized access, personal information of 617 customers leaked.

Sony Bank has suspended digital securities trading after Securitize Japan, the outsourced provider of its digital securities service, detected unauthorized external access to its systems on October 29. The breach exposed personal information belonging to 617 customers, including names for all 617 and names, addresses, dates of birth and account numbers for four of them. Sony Bank said no fraudulent transactions have been identified so far and no leaked data has been found circulating online. The incident is confined to the Securitize-run digital securities system and does not affect other banking services, though the bank has not set a date for resuming trading. The bank is contacting affected customers individually; the timing of the trading restart and the scope of any further fallout are the key things to watch.
