Japanese businesses are facing a wave of major data breaches following cyberattacks. Two separate railway companies disclosed that around 6.09 million and 1.3 million customer accounts respectively may have been compromised. These breaches were traced back to a ransomware attack on IDC Frontier, a software subsidiary of the conglomerate SoftBank.
A secondhand goods retailer, Bookoff Group Holdings, reported that its subsidiary managing membership data was breached, potentially exposing up to 6.43 million customers. Meanwhile, the operator of the karaoke chain Big Echo claimed that personal details of approximately 8.72 million customers could have been accessed due to unauthorized system access via an external contractor.
Adventure Inc., the operator of the travel booking website Skyticket, announced a potential breach affecting about 14.64 million sets of personal information, following a cyberattack on its servers and booking system. The affected data includes email addresses, names, dates of birth, and telephone numbers of customers at JR East and the other three entities. However, Adventure confirmed that credit card and passport numbers remained secure.
The affected companies stated they found no evidence of unauthorized use of the compromised information by third parties.
