A newly discovered security hole may have allowed attackers to hijack the digital wallets of PlayStation Store customers as well as change their passwords and view their personal info.

It's not clear how many—or if any—accounts were actually hacked. Sony says it took "immediate measures" to patch the security hole, adding that it's contacting any users whose accounts may have been cracked. The electronics giant also said it's "very unlikely" that credit card numbers (which aren't fully displayed in user account profiles) were compromised.

According to an alert posted on the U.S. PlayStation site, the security hole could have allowed hackers to access PlayStation Store accounts through a PC, change their passwords, view personal info, and use store "Wallets" to buy content.

Want to know if your PlayStation Network account was breached? Try logging into your account; if you can sign in successfully, you're probably fine, according to Sony. If you're locked out, that's a bad thing—contact Sony customer service at PSN_account_support@playstation.sony.com, pronto.
