Sony has released a new PlayStation Network security update on their EU blog explaining that while PSN members' passwords were not encrypted, they were still transformed using a "cryptographic hash" and that they want to be very clear that user passwords were not stored in their database in cleartext form.
The update also mentions that the story revolving around a hacker selling 2.2 million credit card numbers is false. "One report indicated that a group tried to sell millions of credit card numbers back to Sony. To my knowledge there is no truth to this report of a list, or that Sony was offered an opportunity to purchase the list," said Sony. You can read the full statement after the break.
On Tuesday, April 26 we shared that some information that was compromised in connection with an illegal and unauthorized intrusion into our network. Once again, we’d like to apologize to the many users who were inconvenienced and worried abut this situation.
We want to state this again given the increase in speculation about credit card information being used fraudulently. One report indicated that a group tried to sell millions of credit card numbers back to Sony. To my knowledge there is no truth to this report of a list, or that Sony was offered an opportunity to purchase the list.
One other point to clarify is from this weekend’s press conference. While the passwords that were stored were not “encrypted,” they were transformed using a cryptographic hash function. There is a difference between these two types of security measures which is why we said the passwords had not been encrypted. But I want to be very clear that the passwords were not stored in our database in cleartext form.
To reiterate a few other security measures for your information: Sony will not contact you in any way, including by email, asking for your credit card number, social security number or other personally identifiable information. If you are asked for this information, you can be confident Sony is not the entity asking. When the PlayStation Network and Qriocity services are fully restored, we strongly recommend that you log on and change your password. Additionally, if you use your PlayStation Network or Qriocity user name or password for other unrelated services or accounts, we strongly recommend that you change them, as well. To protect against possible identity theft or other financial loss, we encourage you to remain vigilant, to review your account statements and to monitor your credit reports.
We continue to work with law enforcement and forensic experts to identify the criminals behind the attack. Once again, we apologize for causing users concern over this matter.
Our objective is to increase security so our customers can safely and confidently play games and use our network and media services. We will continue to provide updates as we have them.
What do you think about the newest security update? To me is just seems like pretty obvious information, telling people to change their passwords when the PSN comes back up and that to their knowledge Sony wasn't offered to buy back the credit cards. Even if Sony was offered to buy back the cards, with how they've handled the whole PSN security breach, do you think they would tell the general public about it?
