Sony says it has discovered a security breach affecting 8,500 user accounts in a music entertainment website in Greece.

Sony Corp. spokesman Shigenori Yoshida said Tuesday that personal data including names, phone numbers and email addresses may have been stolen. Yoshida said no credit card numbers have been affected.

Sony shut the website on Sunday and is investigating the attack.

Yoshida could not provide further details.

Sony's PlayStation Network system was hacked last month, affecting more than 100 million PlayStation Network, Qriocity and Sony Online Entertainment accounts worldwide and forcing the company to shut down the popular online gaming and video streaming services.

The Japanese maker of PlayStation 3 video game machines and Bravia flat-panel TVs has said it aims to fully restore the service by the end of May.

The company Monday said it spent $170 million to cover costs that included identity theft insurance for customers, improvements to network security, free access to content, customer support and an investigation into the hacking.

Japanese ISP hit

Sony discovered last week that another of its units  — a mobile Internet service provider in Japan called So-net Entertainment Corp. had also been attacked.

So-net said that someone gained improper access to user accounts and successfully used so-called "So-net points" to obtain goods worth about $1,225.

It said it discovered the activity late Wednesday after customer complaints and cut off the Internet Protocol address behind about 10,000 attempts to break into the system.

The intruder used points from 128 accounts and illicitly checked the e-mails of 90 users.
