Nikkei says new breach exposed 1.83 million personal-information records
The company has reported its third security incident in about a month and said it has not found signs of misuse or service disruption.
Nikkei said a new breach exposed 1.83 million personal-information records, marking its third security incident in roughly a month. The company said attackers got in with stolen credentials on October 7 through a development system, and the affected data was stored in the cloud. Nikkei said 150,000 records contained at least one identifier such as names, email addresses, physical addresses, phone numbers, or birth dates, while the rest lacked identifying data and no credit card details were involved. It notified Japan’s Personal Information Protection Commission on October 11 and said that as of October 16 it had no sign the information had been misused online or that the incident disrupted services.
Why it matters
For the people whose data was exposed, the main change is that Nikkei has confirmed the scale of the breach and told Japan’s privacy regulator. The company also says it has not seen evidence that the information has been misused or leaked online yet, which limits what is known about immediate harm, but does not change that a large set of personal records was affected.
