Sony’s PlayStation Network has once again been targeted by hackers. Chief information security officier Philip Reitinger informed everyone on the EU PS Blog of a large scale hack attempt and warned users to secure their log-in details.
We want to let you know that we have detected attempts on Sony Entertainment Network, PlayStation Network and Sony Online Entertainment (“Networks”) services to test a massive set of sign-in IDs and passwords against our network database.
However, only a small fraction of these showed additional activity prior to being locked by Sony. Reitinger also revealed that credit card details of users were not at all compromised.
Less than one tenth of one percent (0.1%) of our PSN, SEN and SOE audience may have been affected. There were approximately 93,000 accounts globally (PSN/SEN: approximately 60,000 accounts; SOE: approximately 33,000) where the attempts succeeded in verifying those accounts’ valid sign-in IDs and passwords, and we have temporarily locked these accounts.
Locked accounts will be soon issued with password resets. Reitinger believes the combinations being tested have been sourced from another company’s compromised database rather than from the PSN, Sony Online Entertainment, or other Sony networks.
The overwhelming majority of the pairs resulted in failed matching attempts. We have taken steps to mitigate the activity.
We encourage you to choose unique, hard-to-guess passwords and always look for unusual activity in your account.
Sony’s PlayStation Network suffered a severe blow following an attack by hackers this past April. The attack was enough to bring down the PSN for two months and comprised millions of user accounts, including credit card details.
