A Sony server has been hacked to host a website for an alleged phishing scam targeting an Italian credit card company and its users, according to the web security firm F-Secure.

"We know you're not supposed to kick somebody when they're already down ... but we just found a live phishing site running on one of Sony's servers," F-Secure wrote in a blog post.

Basically this means that Sony has been hacked, again. However, the security breach appears to be unrelated to the attacks that took down Sony's PlayStation Network and Qriocity music service, F-secure said.

The attacks on Sony's online services that affected PlayStation and Qriocity users resulted in exposure and possible theft of personal data for more than 90 million customers.

F-Secure added that it has already notified Sony and that it has blocked its customers from accessing the specific malicious phishing URL.

But Sony's headaches are not finished here.. So-Net, the Internet service provider unit of Japan's Sony, alerted customers an intruder broke into its system and stole virtual points from account holders.

Sony announced the latest theft on its So-Net homepage in Japanese on Thursday.

The hackers targeted Sony's Www.so-Net.ne.jp/Point/ page and stole about 100,000 yen ($1,225) from accounts that were attacked. The company said there was no evidence other accounts in the online system had been hacked.

Sony said that the attack started on May 16 and was finished one day later. The company discovered the attack on Wednesday, May 18 and blocked the unathorized access to its servers. Sony has currently stopped the So-Net points exchanges and asks its customers to change their passwords.
