It’s a good thing Sony warned people to be vigilant about their credit cards, because as part of the company’s Tokyo press conference yesterday PlayStation boss Kaz Hirai said that up to ten million customer’s account details could have been compromised.

It’s important to note that these cards are still potentially at risk: there is still no confirmation that any of these ten million cards’ data have been compromised.
While it’s been confirmed that CVV2 details – which are requested as part of PSN transactions, but not stored on Sony’s servers – were not obtained, it’s possible for hackers to obtain the three-digit codes (found on the back of cards) via simple brute force, especially when they have their hands on the rest of the card’s details.
