NTT Docomo reports data leak affecting 440,000 customers
Original: ドコモ 情報 漏洩
NTT Docomo says personal information on roughly 440,000 customers was exposed through its Docomo Hikari fiber service's plala (S course) offering, after an unauthorized access incident at a contractor. The carrier is investigating the breach and notifying those affected. The leak is drawing attention in Japan as the latest in a series of data breaches involving telecom providers and outsourced services.
Why now: The scale of the leak, around 440,000 records, and questions over contractor security are prompting widespread concern in Japan.
