YahooBB - YahooBroadBand which is broadband ISP, and part of Yahoo Japan has confirmed that personal data of 4.5 million of current and past subscribers were leaked. No credit card data or passwords were leaked.

It interesting how bad the damage will be in the long term.

Credit card data isn't too hard to get ahold of - the personal data needed to successfully forge large purchases is the real prize - YahooBB customers, cancel your cards...

Really? Do you mean to say that once one knows a name, address and telephone number, it's easy to learn that person's credit card number? If that is true, isn't it also dangerous to be listed in a phone book? And wouldn't it be just as easy to learn the new number after it's issued?

Methinks your alarm is excessive as is the brouhaha in the news over this event, at least here in Japan. Many companies have had credit card info leaked and gotten less press.

Just got an email from Yahoo BB (I'm a customer).

They say for 4,517,039 customers the following was leaked in relation to an attempted extortion:
1) Customer Name
2) Customer Address
3) Customer Phone #
4) Customer contact email- when applied
5) Customer Yahoo BB email
6) Customer application date

They are allowing customers to change their Yahoo BB mail address and other info free of charge.
