The recent hack of the Sony network has exposed user information on approximately 77 million accounts. The attack, according to an article in the The Telegraph, has potentially exposed passwords and credit card numbers. If this is true, this is “not good”, since it would imply that the passwords and the credit card numbers were not encrypted when they were stored in Sony’s network.
I registered for the Sony network, so apparently my credentials were among the ones stolen during this attack. At the end of this posting is the email message that I received from Sony about the incident. (I have removed some information that is not important for this posting.) The posting recommends changing the account password once the Sony network has been reactivated.
The Sony network required an email address and a password for a user to log into their network. An email address along with a password is used for authentication to other networks, such as LinkedIN or Facebook. Thus, it is possible that some of the accounts compromised in the Sony network attack can be used to hijack non Sony accounts. The below email message from Sony would be better if it recommended that users change all accounts using the same email address and/or the same password used in the Sony network.
What can users do? When registering for networks such as Sony’s, Amazon’s or others, be sure the email adress and password used for authenticiation on one site is not used for authentication on other sites. This means that a user needs to ensure that the userid/password used to log into Facebook is not the same as the userid/password used to log into the Sony network. This will limit the potential risk if one network is compromised For example, my amazon ID is not at risk from this attack since I user different account information for the Amazon and Sony networks.
Here is the email I recieved.
" Valued PlayStation(R)Network/Qriocity Customer:
We have discovered that between April 17 and April 19, 2011, certain PlayStation Network
and Qriocity service user account information was compromised in connection with an illegal
and unauthorized intrusion into our network. In response to this intrusion, we have:
1) Temporarily turned off PlayStation Network and Qriocity services;
2) Engaged an outside, recognized security firm to conduct a full and complete investigation
into what happened; and
3) Quickly taken steps to enhance security and strengthen our network infrastructure by rebuilding our system to provide you with greater protection of your personal information.
We greatly appreciate your patience, understanding and goodwill as we do whatever it takes
to resolve these issues as quickly and efficiently as practicable.
Although we are still investigating the details of this incident, we believe that an
unauthorized person has obtained the following information that you provided: name, address
(city, state, zip), country, email address, birthdate, PlayStation Network/Qriocity password
and login, and handle/PSN online ID. It is also possible that your profile data, including
purchase history and billing address (city, state, zip), and your PlayStation
Network/Qriocity password security answers may have been obtained. If you have authorized a
sub-account for your dependent, the same data with respect to your dependent may have been
obtained. While there is no evidence at this time that credit card data was taken, we
cannot rule out the possibility. If you have provided your credit card data through
PlayStation Network or Qriocity, out of an abundance of caution we are advising you that
your credit card number (excluding security code) and expiration date may have been
... 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
are providing the following information for those who wish to consider it:
- U.S. residents are entitled under U.S. law to one free credit report annually from each of
the three major credit bureaus. To order your free credit report, visit
www.annualcreditreport.com or call toll-free (877) 322-8228.
- We have also provided names and contact information for the three major U.S. credit
bureaus below. At no charge, U.S. residents can have these credit bureaus place a "fraud
alert" on your file that alerts creditors to take additional steps to verify your identity
prior to granting credit in your name. This service can make it more difficult for someone
to get credit in your name. Note, however, that because it tells creditors to follow
certain procedures to protect you, it also may delay your ability to obtain credit while
the agency verifies your identity. As soon as one credit bureau confirms your fraud alert,
the others are notified to place fraud alerts on your file. Should you wish to place a
fraud alert, or should you have any questions regarding your credit report, please contact
any one of the agencies listed below:
