Japan's breach wave widens as Yamato, Nikkei and Times Car report millions of records
Logistics, media, rail and retail firms disclosed new details Friday, with Qilin ransomware suspected in at least one case
TOKYO — More Japanese companies disclosed customer data breaches on Friday, extending a run of cyberattacks that has hit the country this month. Yamato Transport said 5.31 million personal records from its deferred-payment service were compromised, covering about eight years of data from October 2018. Nikkei said about 1.83 million records, including names, addresses and email addresses, were exposed after a cloud service used for system development was accessed fraudulently. Park24, parent of the Times Car operator, said 6.6 million records were affected in its attack. About 1.6 million of those included images of driver's licenses or other ID documents. Park24 will finish deleting those images by the end of October and will change its rules to delete them immediately after verification. Keio, a railway operator, said attackers claimed to have published its data. Outside experts suspect the Qilin ransomware group. Cosmetics maker Fancl and its affiliate reported about 830,000 affected customers.
Why it mattersThe scale and variety of victims point to systemic weaknesses in Japanese corporate data handling, and identity-document leaks raise fraud risks for years.
