Hackers accessed a cloud service used by Japanese media group Nikkei on October 7, using credentials that had already been compromised.
The incident exposed 1.83 million records, though Nikkei says most contained no information that could identify a person.
About 150,000 records included details such as names, addresses, phone numbers or birth dates, and 120,000 included email addresses.
No credit card information was exposed, and as of October 16 Nikkei had found no evidence that the stolen information was misused.
Nikkei revoked the compromised credentials and notified regulators; it is still investigating the breach and says it will contact affected people individually.
