Sony's chief information security officer Philip Reitinger posted on the PlayStation Blog this morning to inform customers that there have been attempts to breach Sony's security. Rather than a full-on hack, this was a large scale automated attempt to test sign in ID and password combinations acquired from compromised lists.
93,000 accounts were potentially affected worldwide. 60,000 of these were PSN or Sony Entertainment Network accounts, while 33,000 were Sony Online Entertainment accounts. Of these 93,000 accounts where access was gained to the account, only "a small fraction" showed additional activity following sign-in. Sony has locked all potentially affected accounts and is reviewing them to determine if they had been accessed in an unauthorized manner. Reitinger notes that users with a credit card on file will not have had this information put at risk, and says that Sony will work with customers who have had unauthorized purchases added to their account to have the amounts restored to their PSN or SOE wallets.
If your account is in the 93,000 potentially affected, you'll have received an email and will be asked to reset your password.
"We want to take this opportunity to remind our consumers about the increasingly common threat of fraudulent activity online, as well as the importance of having a strong password and having a username/password combination that is not associated with other online services or sites," writes Reitinger. "We encourage you to choose unique, hard-to-guess passwords and always look for unusual activity in your account."
