I haven't seen this story making the rounds in the security community. Interestingly, I got this story from a mailing list for a card forum. Apparently, 2.28 million"encrypted payment card account numbers and other details" were stolen OVER 18 MONTHS AGO. Betfair just recently notified their clients. Allegedly, 3.16 million "account user names with encrypted security questions" and 89,744 "account usernames with bank details" were also taken.
An article with more information is here.
Sure, it's good to hear that some information was encrypted. However, a lot can happen in 18 months. If someone has a link to an article with more technical information, I would love to see it.
