4.5 million subscriber names, phone numbers, postal addresses, email addresses and Yahoo Japan IDs were leaked from Softbank Corp., the largest provider of broadband access in Japan, it reported to Reuters.
Toyko police arrested four individuals suspected of stealing the confidential data and demanding a payment from Softbank to avoid it being leaked. An insider is suspected. Softbank's CEO Masayoshi Son accepted responsibility, apologized and took a 50% salary cut for 6 months. Reuters reported that credit card, bank account and password details on a separate database were not compromised.
Softbank said it has since put restrictions on how many staffers can access databases, and upgraded a system of logging access history.
