Tokyo, Oct. 16 (Jiji Press)–More Japanese companies on Friday made announcements regarding customer data breaches due to cyberattacks. Yamato Transport Co. said that 5.31 million sets of personal information belonging to some users of its deferred payment service were compromised in a breach that the logistics firm had first announced on Sept. 29. The affected personal information, including names, addresses and phone numbers, was collected over roughly eight years from Oct. 1, 2018. Business daily publisher Nikkei Inc. said that about 1.83 million sets of personal information, including names, addresses and email addresses, were compromised after a cloud service used for system development was fraudulently accessed. Park24 Co., the parent company of the operator of the Times Car vehicle-sharing service, said that it will finish deleting images of identity verification documents, including driver’s licenses, by the end of this month, following a data breach. The company will also revise its internal rules so that such images are deleted immediately after identity verification is completed. Of the approximately 6.6 million sets of personal information affected in a cyberattack on the Times Car operator, about 1.6 million included images of driver’s licenses and other documents. Railway operator Keio Corp. said that cyberattackers had claimed to have published its information following a system disruption late last month. Outside experts believe that Keio was targeted in a ransomware attack by the international hacker group Qilin. Cosmetics maker Fancl Corp. and affiliate Attenir Corp. announced a data breach affecting a total of about 830,000 customers. Japan Post Co. said information on about 600 users of an online service for requesting investigations into undelivered international mail may have been compromised.
